Jacobus Barbireau

An illuminated copy of the Missa Virgo parens Christi by Jacobus Barbireau; composed in the late 15th century, copied in the early 16th century as part of a gift to Pope Leo X

Jacobus Barbireau (also Jacques or Jacob; also Barbirianus) (1455 – 7 August 1491) was a Franco-Flemish Renaissance composer from Antwerp. He was considered to be a superlative composer both by his contemporaries and by modern scholars; however, his surviving output is small, and he died young.
