thaumaturge

Medieval Latin thaumatūrgus "worker of miracles," borrowed from Late Greek thaumatourgós, going back to Greek, "performer of wonders (as an acrobat)," from thaumat-, thaûma "wonder, object of wonder or admiration, marvel" (probably derivative from the base of théā "sight, spectacle") + -ourgos "performing, carrying out (the thing specified)," going back to *-o-wergos or *-o-worgos, derivative of Indo-European *u̯erǵ- "make, bring about" (whence, as a nominal derivative, Greek érgon "work") — more at theater entry 1, work entry 1
