Iconography is different than "regular" painting. It is intended to be a window onto divine understanding. This icon from 1403 shows the strong Byzantine tradition (all those symmetrical folds of the garments) combined with a new knowledge of proper anatomy (the position of the kneeling disciples). Theophanes the Greek is one of the most famous icon makers in history.
Prayer: Lord, please help us understand the dual nature of your humanity and your divinity as we prepare to walk in your footsteps this coming Holy Week.
