Removed the last supper as it has been noted that this instance of the ceremony was meant to be referencing the Feast of Dionysis, or at the very least, the instance of an Olympian feast in Pagan mythology.

If I'm being honest, this still feels like a bad excuse to me. If you compare the paintings, the ceremony looked so much more like the last supper. Especially with the prominent central figure at the table that even wears a halo (not that Jesus has a halo in the painting, but halos are not really known to be pagan things)
