The Portrait of Daniele Barbaro is an oil on canvas painting by the Italian Renaissance master Paolo Veronese, from c. 1556-1557.

The book standing up is the La Practica della Perspettiva, Barbaro's treatise on artistic perspective.

[1] The other volume on the table is Barbaro's "Commentary" on Vitruvius' De architectura,[2] which has illustrations by Andrea Palladio.

Barbaro's Commentary on Vitruvius was published in Italian in 1556, but the portrait may be linked to the publication of a second edition in Latin in the 1560s.

[3] There is a portrait by Veronese in the Pitti Palace, Florence, which has been described as Barbaro dressed as a Venetian aristocrat, but this identification is not certain.
