 When Armatus met Zeno, however, he was bribed into joining the Isaurian emperor, who promised him the title of "magister militum praesentalis" for life, his son, Basiliscus, the title of caesar, and the qualification as heir to Zeno.After his restoration, Zeno fulfilled his promises, letting Armatus keep his title of "magister militum praesentalis" (possibly even raising him to the rank of "Patricius") and appointing his son Basiliscus "Caesar" in Nicaea.In 477, however, Zeno changed his mind, according to Evagrius by the instigation of Illus, an Isaurian general who had helped Basiliscus' rise and later changed sides to Zeno, and who would have gained by the fall of Armatus.
