The Theorica planetarum is usually considered to be by the Cremona astrologer Gherardo da Sabbioneta, although some authorities ascribe it to the Gerardus Cremonensis who died 1187. Cf. Dict. of scientific biog., suppl., p. 189 for a summary of the evidence.
Both works were first printed in 1472. Cf. The awakening interest in science during the first cent. of printing / Margaret Bingham Stillwell. no. 63, 70.
