What is "hadoard"

Hadoard or Hadoardus was a priest, and presumed librarian (custos librorum) in Corbie Abbey, during the ninth century. He is known for two surviving collectanea, or anthologies of extracts. One of these (now Vatican Reg. lat. 1762) draws primarily from the philosophical works of Cicero. It also contains excerpts from Macrobius and Martianus Capella, as well as an introductory poem of 112 lines that echoes classical poets. A collection of excerpts from St. Augustine and other patristic authorities is preserved in Paris, BnF n.a.l. 13381.
