Back into the Human Anatomy Lab at RUSH Hospital twice this week past. Friday I joined Professor Dr. Christopher Ferrigno as his students worked on their dissection assignments.

In the above drawing of a cadaver with considerable dissection on the charts and abdominal cavity, I chose to create a grisaille, or monochrome Gray scale drawing. This features tone and contour but in lacking a wide range of hues or color, makes distinguishing organs much more of a challenge. You may see this trying to differentiate between the heart, seen just above the chin in this view, and the liver which lies directly behind the heart and to the right of it, again relative to this view. What can give greater clarity when using a monochrome scale, would be 1 – employing a subtle shift in grays from cool to warm. The cool gray having a slight blue cast, while the warm gray more of a brown shade. 2 – The strength or width of you countour lines will help distinguish organs one from the other and foreground from background. The character of the organ structure may also affect the contour. So the main lobe of the liver would be a smooth, softly curving line, but the contours of the small intestines would consist of multiple curves of various radius like a thick ribbon folding back on itself again and again. 3 – the surface textures could be very smooth, striated, spotted, mottled, rippled, dimpled, shiny, or covered with small irregular globules of fat. Paying close attention to these sometimes obvious, sometimes subtle distinction will keep your drawings of human tissue from melding in a confusing mass of goulash.

As students work to access organs deeper within the thoracic cavity they have a need to move the intestines out of their way. They were instructed to gather the intestines into a bundle, referred to by  Prof. Ferrigno as the “bouquet”, and set that to the side, as shown in the drawing above.

Yesterday I had the honor to attend an Artist Anatomy Sketching Session organized by Virginia Ferrante-Iqbal at the RUSH Human Anatomy Lab run by Director James Williams PhD. Before I switched majors to art after three years of college, I had been a bio/chem major. And while I had certainly been in labs and had dissected a few small creatures, I never advanced to the human anatomy labs. The first thing is you will notice a slight hint of formaldehyde but the lab was very well ventilated so that was never an issue. Then you don the gown and enter the main room where there are perhaps a dozen or so tables/gurneys with cadavers in blue tarps. Our subject was revealed and as you can see from my sketches had the skin removed from the body’s left side. A moment of respectful silence and gratitude to the donor, then I got down to business. The session is 3 hours. One aspect I wondered about was my palette selection as I packed my gear the night before. I used Pitt Artist Pens which have a wide range of color but my selection left out some hues I’ll look to include next week. I brought a clipboard as one of my sketchbooks, a Stillman & Birn Nova Series, was a soft cover and wouldn’t have given me much support as I stood to draw while holding my sketchbook. The other book, a Stillman & Birn Gamma Series sketchbook had a hard book cover and was well suited to draw and hold on it’s own. I have lots of anatomy books but the clarity you find in most of those books will be different than your experience looking directly upon a cadaver. Connective tissue and the direction or grain of muscle tissue may prove much more confusing than a diagrammatically rendered illustration. That, will be part of the challenge. To draw as faithfully as you see the forms and tissue, or help articulate the structure. An exciting opportunity. There are openings for this lab which meets over the next seven weeks. My thanks to Virginia Ferrante-Iqbal and Dr. Jim Williams.

I returned to the Human Anatomy Lab at Rush Hospital last night and continued drawing from the same cadaver featured last week. More dissection had taken place, as shown here, where the trapezius, still attached to the skull ( the external occipital protuberance to be more exact) having been laid across the towel covering the cadaver’s head. Other muscles around the shoulder/neck area have been partially removed to show substructure. The main muscle of the buttocks, the gluteus maximus has also been partially removed to reveal deeper tissue and the sciatic nerve. In future drawings I will clearly label the muscle groups, bones and key features.

Well, this may be helpful. I worked with videographer Hiromi Sogo to give y’all some sense of how I manage, or try, to sketch people who are not posing but rather engaged in some activity. This I do and have done, as those who follow me know, for more than four decades. This practice has helped me in many ways, but greatly in one in particular. When I had the chance to draw in court, I was already up-to-speed with capturing people in motion.

Here are close ups of the drawing used in the video: just a note, when transferring the video to this platform, some of the soundtrack drops out; a glit I look to correct and avoid in future videos. Learning curve stuff, my bad.

As mentioned in the video, I number the drawings in the order they were begun. To my eyes, there was a lot of “meat on the bone”, I.e. an interesting looking dude holding great poses about concentration, wearing a shiny, puffy jacket made more dramatic by the raking light that accentuated surface features with the cast shadows of near and mid distant structures. Drawing  multiple perspectives or postures on the same page makes the transition from one position to the next easier as the subject moves and/or returns to a similar posture allowing you to add or complete the drawing. Afterwards, it also makes for better side by side comparisons since you’re not flipping back and forth to compare and contrast drawings.

You can see the preliminary or searching sketch for which I used a light Flesh tone. That establishes the general silhouette and will be a place holder if the subject suddenly moves just after I’ve begun drawing. I managed to knock in a good deal of his face and hair but he moved before I could get to his hand. When he returned to this pose about 45 minutes later, my “notes” were in place and I was able to pick immediately where I’d left off.

Evident in these drawings ing s is my use of several tools, one very important amount them are my fingers as you can see the marks left by my fingerprints.

Those fingerprints create hatch marks that are quite distinct from the hatching created with a stylus be it pen or pencil. Varied marks have great appeal to me in that they can enrich the drawing and  their combined effect is to increase the descriptive nature of the marks. But another, very crucial reason I draw with an array of different tools is to take advantage of the inherent attributes of a given tool and by doing so save myself time. Most important in drawing a dynamic subject where you’ve no idea when your subject could move or altogether leave, is to draw efficiently. Why overwork a small nib when a big brush affords greater coverage. Fingerprints create multiple hatch marks simultaneously that are also very difficult to emulate with the stroke of a pen. An inky finger will come in handy if you should want a smudged tone. Add to this collective of mark making, a variety of hues and the drawing gains in richness and description. For the combined effect simply examine the close up below of figure #5.

Drawings were done done with a Faber-Castell Basic Black Leather fountain pen filled with DeAtramentis Document Black Ink and F-C Pitt Artist Pens on a Stillman and Birn Gamma Series sketchbook (S&B is now a subsidiary of Clairefontaine) which takes ink and pencil nicely and can handle watercolor, plus has a little pebbly surface that creates nice textures when smudging or scumbling.

Some end of the decade urban sketching.
