Odo of Metz
Odo of Metz or Eudes of Metz (fl. c. 806 – c. 811) was a Frankish architect, considered of Armenian origin, who lived in the Carolingian Empire during Charlemagne's reign.
Nothing is known of Odo's life, training or education. It is possible he was of Armenian origin; the tradition may stem from a perceived association between the innovative style of his works and early Armenian churches. There is no concrete evidence of his origins, however.
