 Boethius of Dacia, in Latin Boethius de Dacia or Boethius Dacus (“B. from Denmark / the Dane”) was a master of arts at the university of Paris in the early 1270s, and probably already in the late 1260s. Nothing is known about his background except his nationality. His Latinized name is likely to have rendered the Danish name “Bo”. Some twentieth-century scholars refer to him as “Boethius of Sweden”, but this rests on a misunderstanding of the evidence, as shown by Jensen (1963).
