also worked on the project, which was completed in 1557. His works include: (1542) Exquisitae in Porphyrium Commentationes. (1542) Predica de' sogni, published under the pseudonym of Reverend padre Hypneo da Schio. (1544) Edited an edition of the commentaries on Aristotle's Rhetoric written by his great-uncle Ermolao Barbaro. (1545) Edited an edition of Ermolao Barbaro's Compendium scientiae naturalis. (1556) An Italian translation with extended commentary of Vitruvius' Ten Books of Architecture, published as Dieci libri dell'architettura di M. Vitruvio. The work was dedicated to Cardinal Ippolito II d'Este, patron of the Villa d'Este at Tivoli. (1567) He later simultaneously published a revised Italian edition and a Latin edition entitled M. Vitruvii de architectura. The original illustrations of Vitruvius' work have not survived, and Barbaro's illustrations were done specially by Andrea Palladio, and engraved by Johann Chrieger. As well as being important as a discussion of architecture, Barbaro's commentary was a contribution to the field of aesthetics in general. El Greco, for example, owned a copy. Earlier translations had been made, by Fra Giovanni Giocondo (1511) and Cesare Cesariano (1521), but this work was considered the most accurate version to date. Barbaro clearly explained some of the more technical sections and discussed the relationship between nature and architecture, though he also acknowledged the way Palladio's theoretical and archeological expertise contributed to the work. (1567) Dell'Eloquenza Dialogo (1568) La pratica della perspettiva, a book on perspective for artists and architects. This work describes how to use a lens with a camera obscura. an unpublished and unfinished treatise on the construction of sundials (De Horologiis describendis libellus, Venice, Biblioteca Marciana, Cod. Lat. VIII, 42, 3097). The latter work was supposed to have discussed other instruments as well, including the astrolabe, the planisphere of Spanish mathematician Juan de Rojas, the navigation instrument cross-staff, the torquetum, an astronomical instrument and Abel Foullon's holometer, a surveying instrument.
