(in Jerusalem Delivered). The Achilles of the Christian army. “He despises gold and power, but craves renown” (bk. i.). He was the son of Bertoldo and Sophia, and nephew of Guelpho, but was brought up by Matilda. At the age of fifteen he ran away and joined the Crusaders, where he was enrolled in the adventurers' squadron. Having slain Gernando, he was summoned by Godfrey to public trial, but went into voluntary exile. The pedigree of Rinaldo, of the noble house of Este, is traced from Actius on the male side and Augustus on the female to Actius VI. (bk. xvii.).
