Ordelafo Faliero de Doni, 34th Doge of Venice, ruled 1102–1117.
Like the Latin says: Orfaletrus D(e)i Gra(tia) Veneciȩ Dux. Ordelafo, By God’s Grace, Doge of Venice.
Ordelafo is a one-off name, and is presumed to be the Venetian name Faledro, spelled backwards.
Spelling names backwards as far back as the 12th century. And coming up with Ordelafo. That impresses me.
