the Last Supper was a solemn Pontifical High Mass, with Jesus wearing buskins, gloves, tunic, dalmatic and chasuble, as well as mitre, crosier, ring, etc.   I wonder who were deacon and subdeacon though?  James and John?   Peter and Paul?  What style vestments did Jesus wear?  Roman?  Gothic?  Semi-gothic?  Borromean?  Inquiring minds want to know!
