Cover of Cell 2007

This painting was a special commission by Louis Ptacek. The digital painting made the cover of CELL in January of 2007. The final oil version is also shown on this page. The title of the painting is "Dance of the Clock Gene Proteins." The figures are inspired by vase paintings from ancient Greece, and seals from Sumer. They dance around a very old sundial inspired by the Chaldean hemicyclium. There are twelve dancers, who represent various proteins that become active at specific times of the day or night in order to regulate our circadian rhythm. The sky was divided into twelve parts during the time of Ahaz in Egypt when the Chaldeans were perfecting their sundial. This lead to the division of the day into twelve parts as well (Sundials; History, Theory and Practice by Rene' R.J. Rohr).
