Odo_of_Metz
Eudes (also Oto, Odo, Odon) of Metz was an architect of Armenian origin who lived during Charlemagne's reign in the Carolingian Empire. He is the earliest known architect born north of the Alps. He could have been of armenian origin based on an alleged latin inscription found in the dome of the Palatine Chapel which indicated Eudes came from the land of Noah's ark, but no evidence of the inscription has been found yet.[1][2][3][4][5]
