What is "licario"

Licario, called Ikarios ( Greek: ) by the Greek chroniclers, was a Byzantine admiral of Italian origin in the 13th century. At odds with the Latin barons of his native Euboea, he entered the service of the Byzantine emperor Michael VIII Palaiologos (r. 1259–1282), and reconquered many of the Aegean islands for him in the 1270s. For his exploits, he was rewarded with Euboea as a fief and rose to the rank of megas konostaulos and megas doux, the first foreigner to do so.
