The Grid #4
There is a wave-like motion running through the disciples. Those closest to Jesus express the most intense and varied emotions, their reactions a stark contrast to the more subdued figures at the far ends of the table. The amplitude of this emotional "wave" is highest on either side of Jesus and gradually flattens as it stretches out.
On the left, Judas leans back on his elbow, generating a downward tilt that is counterbalanced on the right by the upright posture of Philip who stands behind James and Thomas.
As the wave moves outward toward the edges of the composition, it looses intensity and gradually flattens.
