Early in his military career, this ruler successfully tricked the adventurer-turned-prince Roussel de Bailleul (15[1])(“roo-sell day BYE-yull”) into abandoning his capital by blindfolding (15[1])him. A history of this ruler’s reign that opens by quoting Sophocles claims he got stabbed in the buttocks while fighting nomads who later helped him win the Battle of Levounion (“lev-own-ee-yun”). This ruler introduced the hyperpryon as a replacement for his empire’s previous debased (15[1])coin, the (*) nomisma. A future ally of this ruler previously routed his right flank at the Battle of Dyrrhachium (10[1])(“dir-ACK-ee-yum”). A laudatory chronicle of this ruler written by his daughter Anna includes an account (10[1])of his appeal to Pope Urban II for aid against the Seljuk Turks. For 10 points, name this Byzantine emperor during the First Crusade. ■END■
