text: Gotta love that odd grasping at straws that people pull out of their hats.....Dan Brown would be so proud.  Oh, wait.....do you suppose Da Vinci was at the Last Supper?
  
  If you study Da Vinci, you will see he often painted effeminate looking men.  There is much speculation for that, but it is a fact.  I wouldn't put too much stock in a painting from the 15th century for clarity as to who was seated next to Jesus - Dan Brown notwithstanding.
  
  As far as Scriptual clarity?  Try Matthew 26:20.
