Diego de Astor
Diego de Astor, of Toledo, studied under Domenico Theotocopuli, and in 1606 engraved, under his superintendence, a 'St. Francis,' after Nic. de Vargas. Astor was engraver to the Mint of Segovia, and was also employed to engrave the royal seals. Of his plates we may notice the titlepage to Colmenares' 'Historia de Segovia' (Madrid, 1640), and that to Bonet's book on 'Speech for the Dumb,' one of the best works of the kind.
