Mystic Marriage of Saint Catherine (Lotto, Munich)

Mystic Marriage of Saint Catherine is a 1506-1508 oil on panel painting by Italian Renaissance artist Lorenzo Lotto, signed on Catherine of Alexandria's broken wheel (centre foreground) "Laurent.[ius] Lotus F.[ecit]". It is known to have moved from the Würzburg Residence to the Hofgartengalerie in 1804 and then to its present home in the Alte Pinakothek in Munich. 
A workshop version of the painting is also in the Museum of Fine Arts, Boston.
