Contancin, Cyrique a French Jesuit missionary, was born at Bourges in 1670. In 1700 he was sent to the Chinese missions, and did not return to France until 1731, when he was brought back by some affairs connected with his order. Being appointed superior-general in China, he went to Port Louis, where he took ship November 16, 1733, but died at sea a few days afterwards. His long sojourn in Asia afforded him opportunity for collecting curious documents, and these were published in the Lettres Edifiantes. See Hoefer, Nouv. Biog. Generale, s.v.
