Archbishop of Poggio, an ecclesiastical warrior, who with William, Archbishop of Orange, besought Pope Urban on his knees that he might be sent on the crusade. He took 400 armed men from Poggio, but they sneaked off during a drought, and left the crusade (Book xiii.). Ademar was not alive at the time, he had been slain at the attack on Antioch by Clorinda (Book xi.); but in the final attack on Jerusalem, his spirit came with three squadrons of angels to aid the besiegers (Book xviii.).
