In 1489 he was accused of magic before Pope Innocent VIII., and had to secure the good offices of Francesco Soderini, Ermolao Barbaro, and the archbishop Rinaldo Orsini, in order to purge himself of a most perilous imputation.
In this interval the use of the lens was discovered and clearly described by Daniello Barbaro, a Venetian noble, patriarch of Aquileia, in his work La Pratica della perspettiva (p. 192), published in 1568, or twenty-one years before Porta's mention of it.
The lens used by Barbaro was an ordinary convex or old man's spectacle-glass; concave, he says, will not do.
That Barbaro was really the first to apply the lens to the camera obscura is supported by Marius Bettinus in his Apiaria (1645), and by Kaspar Schott in his Magia Universalis (1657), the former taunting Porta with the appropriation.

The narratives of Caterino Zeno, Barbaro and Contarini, envoys from Venice to the court of Uzun Tlasan, are in this respect especially interesting.
Barbaro and Contarini met at Isfahan in 1474, and there paid their respects to the shah together.
This account is confirmed by Angiolello, a traveller who followed his countrymen Barbaro and Contarini to Persia; and from the two authorities combined may be gathered the further narration of the murder of Rustam and usurpation of the throne by a certain Ahmad, whose death, under torture, six months afterwards, made way for Alamut, the young son of Uasan.
