Juno was the consort of Jupiter and chief goddess on Olympus. She was the patron of fidelity in marriage, although the wife of an erring husband.
She was one of the three goddesses from whom Paris was to select the most beautiful. Her attribute is a peacock, as in Rubens's painted two versions of the 'The Judgement of Paris' that are in the Collection: one was painted in 1600 and the other in 1632.
In Jupiter's numerous adulterous relationships Juno is often to be seen spying on him while he makes strenuous efforts to escape her. In Tintoretto's 'The Origin of the Milky Way' Jupiter has put his infant son, Hercules, the offspring of the mortal woman Alcmene, to Juno's breast in order to make the child immortal.
