The story of Leda and the Swan was the subject of two compositions by Leonardo da Vinci from perhaps 1503–1510. Neither survive as paintings by Leonardo, but there are a number of drawings for both by him, and copies in oils, especially of the second composition, where Leda stands.
Leonardo began making studies in 1504 for a painting, apparently never executed, of Leda seated on the ground with her children. Three sketches of Leda by Leonardo exist:
It has been proposed that Leonardo's Chatsworth sketch for Leda and the Swan (pictured) may have been inspired by the Laocoön Group, the ancient sculpture discovered in 1506: there is a similar twist to the subject's body; the curve of the swan's neck recalls the snake's lithe body in Laocoön's hand; the rape by Zeus evokes the forceful attack of the serpents; and the child next to Leda's knee resembles Laocoön's son on the right, who also has a sheer break at the wrist. A completed copy of Kneeling Leda with her Children by Giampietrino is kept at the Museumslandschaft Hessen Kassel, Gemäldegalerie Alte Meister, Kassel (c. 1515/20, oil on wood, 128 x 106 cm).
In 1508 Leonardo painted a different composition of the subject known as Leda and the Swan which depicted a nude standing Leda cuddling the swan, with the two sets of infant twins and their huge broken egg-shells. The painting is lost, probably deliberately destroyed, and was last recorded in the French royal Château de Fontainebleau in 1625 by Cassiano dal Pozzo:
A standing figure of Leda almost entirely naked, with the swan at her and two eggs, from whose broken shells come forth four babies, This work, although somewhat dry in style, is exquisitely finished, especially in the woman's breast; and for the rest of the landscape and the plant life are rendered with the greatest diligence. Unfortunately the picture is in a bad state because it is done on three long panels which have split apart and broken off a certain amount of paint.
The picture is known from many copies, of which the earliest are probably the Spiridon Leda, perhaps by a studio assistant and now in the Uffizi, and the one by Cesare da Sesto at Wilton House in England. Other copies by Leonardeschi include:
