[Portrait by F. Diodati]
Geneva, Samuel de Tournes, 1680. Original print (21.3 x 17.0 cm; printed surface 19.3 x 15.0 cm), printed on one side.
Rare portrait of the eminent Irish scientist Robert Boyle (1627-1691). Engraved by the deaf-mute French artist François Diodati (ca. 1647-1690), and subtitled "Robertvs Boyle nobilis Anglvs". This seems to be a copy of William Faithorne's 1664 engraved portrait, with Boyle's air pump in the background. Faithorne (1616-1691) is principally known as a portrait engraver. Diodati's rendering of this portrait has been identified as the frontispiece of Boyle’s "Opera Varia quorum posthac extat catalogus", published in Geneva in 1680. Some light, marginal spotting, otherwise a very good copy.
