The reasons for this placement are debated, but some theories include:
* Symbolism: John is often seen as the "beloved disciple" in the Gospels. Placing him close to Jesus could symbolize his closeness to the Lord.
* Composition: John's position helps balance the composition of the painting, creating a sense of symmetry and movement.
* Perspective: Da Vinci used linear perspective to create a sense of depth in the painting. John's position in the foreground helps emphasize this effect.
It's important to note that there are many interpretations of Da Vinci's "The Last Supper", and no single answer can definitively explain John's placement. However, it's clear that Da Vinci carefully considered the composition and symbolism of the painting.
