Still Life with canvas, pallet, and brushes

Aristotle said in his Poetics, “The aim of art is to represent not the outward appearance of things, but their inward significance, and this, and not the external manner and detail, is true reality.”

He spoke mainly about poetry, which was the highest art of his age, but his words also apply to the fine arts. Today, many people are still mesmerized by artists who practice various styles of realism, but they overlook the artists who show us the realities of emotion and inner vision.

The good news about art.

“Art enables us to find ourselves and lose ourselves at the same time,” said the spiritual writer, Thomas Merton. Some people use art as a cathartic exercise, and pour out their inner emotions on the canvas or their chosen media. Jackson Pollock’s drip paintings and Van Gogh’s late works are good examples of emotional expression. We all know folks who have a project going in their garage. They go work on “that worthless piece of junk” to focus their attention and energy on fixing something on which they can make a difference, instead of getting tied up in knots about things they can’t change and must accept. Gardening and knitting are also good hobbies for focusing this energy.

We know our nervous system grows to the modes in which it has been exercised. This is what we call building a habit over time. Just as a child doesn’t walk straight out of the womb, they have preparatory skills that must be acquired by stages as they grow. Exercising their muscles by rolling over also helps to strengthen their necks to hold their heads up. Crawling leads to pulling up, and that leads to letting go to learn balance.

Each time a child repeats these movements, he or she will simplify the movements required to achieve the needed result, make them more accurate, and diminish fatigue. In this, they’re building habits that bring them closer to walking. Rushing them to achieve “early” walking actually puts them behind cognitively.

Not only are there twenty five body parts in a baby’s body that are used in the crawl movement, but crawling also strengthens the hip sockets, so the baby will have a strong platform on which to stand. Crawling helps the corpus callosum, which is a band of nerve fibers between the hemispheres of the brain. Criss-cross crawling on the knees and hands stimulates the corpus callosum to develop in a balanced way, facilitating the hemispheres of the brain to communicate. These cross lateral movements work both sides of the body evenly and involve coordinated movements of the eyes, ears, hands, feet, and core muscles. This helps support cognitive function, problem solving, and ease of learning. Exploring the floor in a baby proofed home allows your baby to achieve his or her optimal potential.

Gail’s Painting

“Practice makes perfect” is only as true as the practice is directed in a true direction. This is where a teacher, a parent, a coach, or a spiritual guide comes into play. Only one who’s been led well can lead others with grace. We don’t tear down the learner, but ask questions, give guidance, help them see alternative paths, and allow them a safe place to explore their choices.

Art class isn’t brain surgery. No one will die if the painting isn’t successful, and no one’s salvation is at risk if the painting doesn’t come out the way we hoped it might. Art class is a safe place to take risks, unlike jumping from a tall tower without a parachute. Learning to accept failure on our canvases and coming back next time to try again is a mark of resilience and courage. Every time we fail closer to our target, we realize we’re gaining on it! We never say I CAN’T in art class.

Crawl before you Walk or Run

The sad reality is we can teach and expand the horizons of young people up til the age of 25 or 30. After that, they seem to lose energy and desire to learn more or to change. They “habitually” repeat their previous acts, for good or for ill. We’ve all heard the old saying, “You can’t teach an old dog new tricks.” Those of us who are no longer young have sometimes been accused of being set in our ways. Some of us are afraid we won’t excel at a new challenge, for we’ve always been held to a high standard of achievement. Since none of us will be the next Georgia O’Keefe or Leonardo da Vinci, we can set that worry aside. They both had more years to practice than we have left in front of us. Instead, we should give our remaining time our most focused attention, so we can get the most from our experience.

My high school chemistry book had the same information in it which my daddy’s college chemistry book covered. He was amazed I was learning “advanced” ideas at my young age. In 1982 R. Buckminister Fuller introduced the idea of the “knowledge doubling curve.” Up until 1900, knowledge doubled every century. By 1945, knowledge doubled every 25 years and by 1982, it doubled every year. Some say it’s now doubling twice a day! The newest computer we buy off the shelf today is already obsolete.

We can’t train our students for the jobs of today because these jobs likely won’t exist tomorrow. We need to train people to be lifetime learners instead. Luckily, we don’t have to know all things, but we do need the skills to find the knowledge and sort through the best sources for the best possible information.

1930-2006

Today, knowledge we acquire in high school, college, graduate school, and our last job may already be obsolete. (I’m one who still grieves the loss of Pluto as a planet; it exists but is a dwarf planet in the Kuiper Belt). This is especially true in fast moving fields like technology. As futurist Alvin Toffler wrote, “the illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.”

This means all of us will need to become lifelong learners or we’ll risk losing touch with an ever evolving world. Maybe we think our brains can’t handle something new, for we’ve heard about the effect of aging. Cognitive process studies with older brains show learning, memory, and problem-solving in humans are often less efficient in these areas.

However, it has recently been established that dogs show many of the same kind of age related changes that humans do. A study in Vienna showed that older dogs learned new tasks just as well as younger dogs, although they took longer to do so and required more repetitive corrections. This aptitude is also known as “resilience training.”

I think it’s also important to know why we want to keep our brains agile as we move into our later years. John Wesley was fond of repeating William Law’s summary from the Practical Treatise on Christian Perfection,

“Do all the good you can, to all you can,
by any means you can, as long as you can.”

Because Wesley was better known than William Law, this quote is now attributed to Wesley alone. We Methodists have made it our own, however, and have carried its banner around the globe in our world wide mission efforts made possible by our Connectional ministries. Wesley thought enough of Law’s writing to reprint 19 editions of his work.

My late mother, at the age of eighty, learned how to use a laptop computer. She was motivated because she wanted to see emailed photos of her grandchildren, but then she realized she also could find recipes. When a child in her hometown needed a Mercy Flight, she used her new skills to get him transportation to an out of state hospital for treatment. I occasionally had to reteach her on how to double click quickly on her icons, rather than slowly, but she finally caught on.

If we want to keep our brains agile throughout our middle, silver, and golden years, we always need to try new things. Doing art challenges makes our brain build new neural pathways. Every time we look at a still life or a landscape, we have to make multiple decisions: what shapes do I see—circles, squares, triangles, or rectangles; how do these shapes relate to one another on the plane of our canvas; what is most important; what colors will I use; what emotions do I want to express; and where will I begin?

Eventually, we will find our “style.” We don’t find a style by copying another’s work, but we create enough works until our hand becomes one with our spirit. Since God has placed a special spark of God’s own creative Spirit within each of us, eventually we’ll experience the joy of being one with God when we are in our painting moments. As Paul said to the Romans (8:16):

“The Spirit Himself bears witness with our spirit
that we are children of God.”

Last Friday we had a simple still life as our inspiration. Half our class was out sick with spring pollen troubles, but it was good to see those who could come after a two week hiatus. After a brief show and tell to get us inspired by other artists’ takes on the subject for the day, we got started. I reminded everyone not to make the fruit too tiny, so it wouldn’t get lost on the canvas. I believe everyone succeeded with this goal!

Mike’s painting

Mike painted his whole canvas with one brush. This gave the fruit a certain texture with contrasting colors, and the background, which was in a close value, didn’t show much brush strokes or texture. I like the perspective he chose, which brings the viewer in close to these fruit.

Gail tried a larger canvas with bolder colors than she normally uses. It was more dramatic and stronger in contrast than usual, while she kept her smooth strokes of paint as usual. She also took a view from above.

Cornelia’s Fruits

I stuck to a traditional rendering of the still life, since I do many abstract paintings in my own studio. I’d call these two Day and Night, for the Apple is quite awake and the Pear seems to need a little nap. It’s a study in contrasts: red and green, blue violet and yellow orange—a color wheel study masquerading as a still life.

Next week we’re in the season of Lent. As Christ turns his face towards Jerusalem, we’ll begin a study on the icons. This will be accessible and interesting. You’ll end up with your own icon for your personal worship center also.

Joy and Peace,

Cornelia

Year End Art Class Notes

adult learning, Arches National Park, arkansas, art, Christmas, color Wheel, Creativity, Faith, holidays, Imagination, inspiration, Ministry, nature, Painting, photography, shadows

While some are counting the days until Christmas, some of us are are counting the remaining days left in the old year of 2022. Somehow I always get a cleaning burst of energy around the end of the year. Maybe I hear my mother’s voice urging me, “Let’s get the house straightened up, so Santa will find it neat and clean. There’s no way the jolly old man can find the tree when the house is in this much mess!”

My mother’s idea of a mess was a line not perpendicular to its base, or a fragment of paper left on the table. She mostly cleaned to the grooves while my grandmother was alive, for she slacked off after Nannie passed on. The Christmas tree was ensconced in the NONO ROOM, also known as the living room. It acquired the NONO nickname because our parents never let us into it, for we weren’t allowed to touch anything inside it. We lived in the den, like the pack of wild animals we were. We weren’t raised by wolves, but our parents were never able to wring the wolf out of their brood.

I confess I still organize my large spices by size on one shelf and the smaller ones alphabetically on another shelf. I can’t understand anyone who sets their spices on the shelf willy nilly, so they have to search for them every time. Then again, I sort my paints by color and temperature. Organization is one thing I did learn from my folks, even if I didn’t inherit an obsession for daily cleaning.

However, with less than two weeks before Santa comes to visit and Christmas Eve services will bring the birth of Christ to mind once more., my inner mother began to notice strange flecks of dust on the high cabinet doors, as well as dust bunnies rolling out from behind the sofa. Some people have visits from the Ghosts of Christmas Past. My mother comes to visit me. At least I can still climb ladders.

While I’m cleaning up the house, I should catch up on some art works our Oakland UMC art class has been doing. I took off for a month to visit California, came down with a couch bug that made me so congested I couldn’t think, paint, or do doodly. For some reason, Mike moved faster than I could get my camera out, so I don’t have all his photos. Also, sometimes he was tied up in court doing good for others. I promise to do better in the New Year.

Delaunay: View of Paris, Eiffel Tower

The following three paintings began with the idea of circles and lines. As usual, I showed a few different examples from well known artists whose work hangs in museums. This quality inspiration helps students come up with better ideas.

Gail’s Circles

Gail combined her lines with her change of colors. Those boundary lines set up a line which carried through the subtle colors of the background. Limiting her color scheme helps to define these lines. She likes to plan her ideas out in her head first, imagine how they will look, and then paint.

Mike’s circles and lines in the image below reflect his more exuberant personality. Using both the compass and the ruler, he came up with a variety of circles and lines. Mike paints as the spirit moves him. Whatever feels good, that’s where he goes next. He’ll adjust as he goes.

Mike’s Circles

Either of these methods are fine. If one doesn’t get you down the road to the place you want to go, then maybe it’s time try a different route. I never force anyone down a particular fork in the road. I let them explore in one direction until they learn all they can or hit a dead end. Then they can follow the “road not taken.” Everyone gets to try both roads eventually, and learn the ancient wisdom, “All roads lead to Rome.”

This Road May Lead To Rome Eventually

In the art world, “Rome is the fullest experience of both order and emotion.” Some of us prefer one over the other, just as I prefer order in my spice rack, but I’m willing to throw the spices into the soup by sight and not by measuring spoons. We can get too organized or too exuberant, as the Greeks were fond of saying, “The middle path is safest and best.”

Klee: In the Beginning

During this time, the Russian attack on the largest nuclear power plant in Europe was ongoing. Not only was the electricity at the plant cut, an act which blacked out Ukraine and much of Eastern Europe, but it also threatened the stability of the nuclear reactors there. The Ukrainian engineers at the plant were prisoners of foreign soldiers, who knew nothing about the dangers of their stronghold. The world held its breath as fighting broke out around this sensitive target.

Cornelia’s Ukrainian Power-plant Under Attack

Thanks to satellite imagery, today we can see via the internet, what we waited to see in newsreels at the theater, the last time we fought on European soil. We had to wait until the evening news to see film from Vietnam. Now cable news breaks every half hour with the same old news and we might get an update if we’re lucky. Not all can afford to send reporters to distant lands anymore.

By the grace of God, that power plant still stands. However, Europe and Ukraine will have a cold and costly winter. We should not complain if our prices rise, for it’s a small price to pay for democracy and freedom. There are still nations who would oppress smaller countries, just as the Roman Empire did back in the time of Christ’s birth. As we remember in Matthew’s story of The Visit of the Wise Men (2:1-2):

In the time of King Herod, after Jesus was born in Bethlehem of Judea, wise men from the East came to Jerusalem, asking, “Where is the child who has been born king of the Jews? For we observed his star at its rising, and have come to pay him homage.”

This information led Herod to kill all the innocents, the children under two years old in and around the town of Bethlehem (Matthew 2:16-18). Brutality and mass executions aren’t a recent invention of despots desperate to retain power at any cost. The ethical term is utilitarianism, where one uses others as means to gain their own ends. The test question for this type of ethics is “Does the end justify the means?” At what point can you excuse bad or corrupt behavior to get good results?” A moral person answers, “I prefer good means for good ends and will use those unless I’m in a life or death situation.”

I returned, no worse for wear, from my vacation and texted the group to bring a vacation landscape photo to work from. Of course, Gail brought her latest vacation dream destination and Mike brought several island maps to combine into one image. It was the same island where he and his wife had vacationed, but one had tourist attractions, another was history, and the other natural beauty. He has a flair for combining things. Unfortunately, his busy life gets in the way of keeping all his art supplies in one place, so between his work chaos and organizing chaos, plus my slow phone draw, I failed to get his interesting map. It was a good idea.

Gail’s Mars Elevation

The new Mars rover has been sending back some awesome images. The folks at NASA must be over the moon, without a rocket. Gail worked on this elevation image for two weeks, with colors representing different heights in the landscape. It’s a good copy of the image. In the new year we need to go back to three dimensional work again, but we have had fun with color mixing and texture.

Cornelia’s Western Landscape

While out west, I visited as many national parks as I could manage. I did see many volcanoes and convened in a cave, plus I visited Roswell, NM, but wasn’t abducted by aliens. I was impressed with Arches National Park, and hiked about it most of a day. It’s a stark place, with strong rock formations jutting into a brilliant blue sky. The bright sunshine makes strong patterns of light and dark across the landscape. Most of what grows out in the desert is short grasses or a scrub brush, but on occasion, I would find a gnarled tree in dark shade.

Gail’s Christmas Tree

At Mike’s request, we made Christmas cards, but he had to work that day. Probably helping someone with legal matters, because that’s his calling. Gail and I had fun working on the cut paper cards. I was thankful she brought me a coffee. Whatever bug I had took a while to clear my system. Caffeine helped. She rearranged these triangles several different ways on a horizontal plane and never felt satisfied with the way they looked. Because she was wise enough not to glue them down first, she could see her ideas weren’t hitting her happy place.

Then she turned everything straight up, and organized the design on a perpendicular. Now her tree has its happy red birds, a sequin star, and little trees in the background.

Cornelia’s Card

I brought one of my many boxes of colored paper from my scrapbook stash. I know the Christmas colors are red and green, but I made an Advent Tree. This is why it’s violet and pink and blue. Anyway, we don’t have to follow the rules for Christmas trees. If we want a pale purple tree, we can have one. It’s our tree. Santa will still put a present under it, and the color of our tree doesn’t impair our salvation. A nativity set looks just fine under any color tree.

I know we have at least one more class in December on the 16th. Depending on if my plumber is coming over on the 23rd, we might not meet that day. He said he’s behind, so I don’t know. I’ll be on vacation on the 30th, so we’ll see each other in the New Year of 2023!

I always say, “if I ever get totally organized, the world is coming to an end.” Maybe it’s the providence of God that I always bite off more than I can chew, because I’m never totally organized! But I am going on to organization.

Joy, peace, and a better filing system,

Cornelia

Color Theory Paintings

adult learning, Altars, art, color Wheel, Creativity, Faith, Hilma af Klint, Imagination, inspiration, Ministry, mystery, Painting, shadows, Spirituality

Cezanne: Four Apples, 1880-1881, oil on canvas

Cezanne once said, “We live in a rainbow of chaos.” Perhaps he meant we’re surrounded by colors, in various and sundry shades, and through art, we try to find some order to this chaos, even if our resulting work seems outwardly disorderly. In his own lifetime, Cezanne was accused of being a madman, “afflicted while painting with delirium tremens.” His response was to shrug off the guardians of the Academy: “With an apple I want to astonish Paris.” He worked in isolation for a very long time, only gaining financial success in the last ten years of his life.

Jackson Pollock: Number 32, 1949, auctioned in 2018 at Sotheby’s

Another artist who broke ground is Jackson Pollock. When we view a Pollock action painting, we realize there’s actually an order to this chaos. The drips and pours are more like calligraphy and live in tension with one another. They vary in color, size, and energy, not unlike a song. The action paintings are not just “drip paintings,” but energies expressing emotions by means of fluid dynamics. This is why we don’t say, “My grandkid could do this.” People try to forge Pollocks and fail. Even Pollock had difficulty creating these unique works, the best of which belong primarily to a two year period when he refrained from his alcohol habit, which affected his depressive disorder.

As compositions, each of Pollock’s drip pictures simultaneously dissolves into a chaotic jumble of individual lines, while also coming together as a structurally uniform, whole field. We’re mostly used to works best viewed from a single fixed point, such as a High Renaissance painting. Instead, to view a Pollock, we must move across the whole surface, and look deep into the layers. His works draw their audience in to inspect the details closely, passage by passage, and at the same time overwhelm the viewer with their monumental size. Their coloristic and textural richness emphasizes the expansive surface, yet the elaborate and totally visible overlay of multiple layers of paint (and sand, cigarette butts, glass, and other materials) create a very real depth and space. It’s definitely not your grandchild’s artwork.

HANS HOFMANN: Elysium, 1960, oil on canvas, BLANTON MUSEUM OF ART

Hans Hofmann, a 20th C American abstract expressionist, once said, “Colors must fit together as pieces in a puzzle or cogs in a wheel.” Often we use the colors straight out of the tube, or we flail around trying to figure out which yellow and which blue will give us the shade of green we want to use. Experience is the best teacher, for learning how to see the colors of life is like solving a puzzle that doesn’t have a photo for a guide. Once we begin to recognize their composite colors, we begin to see the order in the midst of chaos. Then we have the cogs to the wheel and it will turn the next wheel in good order. Experience becomes our Rosetta Stone for decoding the other mysterious languages of color we hear around us every day.

Color Wheel with Neutral Grey at Center

One of the cues we’ve come to recognize in our painting class is the color of our brush wash water. If it’s a lovely neutral gray, like the center circle in the wheel above, we’ve balanced the warm and cool colors on our canvas. Most of our group in attendance chose colors from this wheel.

Paul Klee: Watercolor Word Study

We saw a number of color theory examples from history, including Paul Klee’s geometric watercolors, which vary from color blocks, landscapes, and written images.

Hilma af Klint: Primordial Chaos, Number 7

A little known colorist is the Swedish artist, Hilma af Klint, who was one of the earliest abstract painters. She developed a language, or visual imagery, to share the spiritual experiences she received during her participation in automatic drawing. As with many others of her era at the turn of the 20th century, she and her friends, in the group called The Five, mixed elements of traditional Christianity with seances and beliefs in a mystical guiding higher spirit. If she lived today, we’d likely call her beliefs “new age.” She also incorporated new advances in science for her time in her explorations.

Hilma af Klint: Altar Piece, Number 1

Her work for The Temple was heroic in size, with each of the 193 paintings measuring about 7 x 9 feet.These were completed between 1906 and 1915. The whole sequence can perhaps be understood as af Klint’s pursuit of an original “oneness,”or the basic unity which she believed existed at the world’s creation. She believed this integrity had since been lost, giving way instead to a world of polarities: good and evil, woman and man, matter and spirit. In her work after 1912, af Klint seemed to move stylistically away from techniques related to spirit channeling, such as the fluid lines of The Five’s automatic drawings. Her use of Christian iconography and geometric forms increased. By 1917, af Klint stopped producing art through a spirit altogether. Her 2,000 plus works are owned and administered by The Hilma af Klint Foundation in Stockholm, Sweden.

Dusty: Circle in Space

Dusty used a plastic plate to draw his circle. This plate served a secondary purpose as well: it was also his palette to mix his colors. “Art imitates life, even in abstraction.” He used the ruler to measure out equal pie shaped segments, and divided the background planes. I almost stopped him in the midst of his planning, but I wasn’t about to stop that train of thought. I could only admire it for its balance and symmetry. He mixed the shades of the colors, and filled in the spaces. Then he added a few “motion” marks to indicate the movement of the disc in the atmosphere.

Gail: Sun and Waves

Gail pulled a plastic French curve drawing shape out of her toolbox to make the unique shapes in her painting. The blue and green curves are the waves of the sea and the central oranges of the resulting negative shape is the sun above the water. I always appreciate her paintings, which connect to her love of nature and have a sense of order to them.

Lauralei: Geometric Shapes

I think I have this painting right side up. I followed the path of the brush strokes. Lauralei wins the prize for most different number of colors mixed on the palette. So often we get accustomed to using the same familiar colors over and over. Everyone had a café au lait colored interior two decades ago, then we all went white, and gray predominated for a while. Maybe soon we’ll paint our homes actual colors instead of following the crowd.

Mike: Rainbow Cross

Mike had this idea percolating in his mind before he came to class, but didn’t have time to work on it at home. As soon as he saw our inspiration works, he decided to follow his inner guide, which had opened this image to him. He took the ruler to mark off some guide lines, then focused on bringing this idea to life. The radiating energy bolts of dynamic rainbow colors coming from the cross remind us of God’s love in Jesus Christ for all things and all people. We’re also one in Christ and belong to the one family of God, no matter how we worship, or what our understanding of God is.

Cornelia’s First Stage: Light and Dark

I began my little painting as a homage to Klee, but I didn’t get far in the 90 minutes we have for painting. I attempted to leave the negative space for the letters, but my brush was either too large or my painting surface was too small for the text I chose. I brought it home and worked another six or seven hours on it in the following week.

Cornelia’s Final Stage: Light and Dark

In the quiet of my studio, I realized I wasn’t paying attention to the emotions of the words, but only to the technical aspects of mixing the colors. I reread again my text from Luke 1:78-79:

“By the tender mercy of our God,
the dawn from on high will break upon us,
to give light to those who sit in darkness
and in the shadow of death,
to guide our feet into the way of peace.”

At this time, I saw the upper half needed to be light, while the lower part of the painting needed to be in darkness, since the two verses broke in this direction. This also gave my painting a landscape feel, as if the dark earth hadn’t yet seen the dawn of God’s light. As I painted, I began to lose the sense of the letters and the words, and the patches of color became more important than trying to keep the sentence legible.

I’m very impressed with this group, who’ve taken to heart my teaching mantra: Everyone will find their own voice if they engage in creative thinking and do the work. In the spiritual life, we’re saved by faith, but in art, we do find “works righteousness.” Amazingly, we get better the more we practice, especially if we have positive critiques and goal oriented lessons designed to help us grow. This provides fertile ground to awaken the spirit living within each of us, so that we can become co-creators in God’s renewal of the world. Maybe Hilma af Klimt was on to something special after all.

Our next class will be The City. We can either treat this as a lesson in perspective, poster design, abstraction, or a close up view of a building. Vacation photos are a good resource to bring, if you have a special place you want to remember. Antique photos are good too. Till next time, keep your hearts full of

Joy and Peace,

Cornelia
