Giotto, The Arena Chapel Frescoes: St. Joseph and the Rods
Scrovegni Chapel, Padua, Italy
St. Joseph is man on the far left with the beard and a halo, waiting patiently while the other men, all much younger, present their rods to the high priest. One version of the legend has it that a dove burst forth from Joseph's rod, signifying that he was chosen to be Mary's spouse. In another version, more commonly pictured, it is a flower that bursts out from the rod.
