Maundy Thursday Meditation - The Lord's Supper

How do you picture the Last Supper?  I suppose I am not the only person who sees that last night of Jesus before His crucifixion as da Vinci's painting by that name.  A quick look through history at other artists' renditions of this moment present the same basic image: Jesus and His twelve disciples around the table. Even ignoring the recent silliness of Dan Brown's novel The da Vinci Code I think it's time to reconsider the image in light of what was really going on.
