Medusa - A Leonardo da Vinci TextMaster. 1/1.

Medusa is described by Leonardo da Vinci's biographer Vasari as being one of his earliest works, painted before 1500, and is thought to be a motif he painted twice: once on a wooden shield, and once with oils on canvas. Either or both paintings are believed to have been held in the collection of Cosimo I de' Medici of Tuscany, the second Duke of Florence between 1553-59, but was however lost in the second half of the 16th century.
