Giotto, The Arena Chapel Frescoes: St. Joseph and the Rods
Arena 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.
This panel is the third from the left on the upper register of the north wall. It is preceded by the Presentation of Mary in the Temple and followed by the Prayer of the Suitors.
