In this article a drawing by Palma il Giovane, now owned by the Staatliche Graphische Sammlung in Munich, is identified as a study for a painting by the same artist. The present whereabouts of this painting, which early on in the 17th century was in the collection of the Amsterdam merchant and art-lover Hendrick van Os, are unknown. Identification of the drawing was facilitated by the lengthy description of this work in Karel van Mander's biography of Palma Giovane in the Italian Lives of his Schilderboeck (Haarlem 1604). Van Mander describes the painting as showing Venus, Juno and Minerva seated at a table, while the angry Discord has just thrown the apple of discord in their midst. His description of the Van Os painting conforms perfectly, almost down to the smallest detail, with the Munich drawing. Van Mander, during his entire stay in Italy, never visited Venice. For his notion of Venetian painting he relied largely on the information he received from visitors to Venice and its surroundings or on Venetian works he had seen elsewhere, either in other Italian cities or in the Netherlands. For his description of Palma Giovanc's artistic skills Van Mander could rely on his firsthand knowledge of the painting owned by Hendrick van Os.
