Nicolas d'Orbellis

Nicolas d'Orbellis was a French Franciscan theologian and philosopher, of the Scotist school.

Biography
He was born about 1400. He seems to have entered the monastery of the Observantines, founded in 1407, one of the first in France. He appears to have been professor of theology and philosophy in the University of Angers, where he enjoyed great reputation as an expounder of the teaching of John Duns Scotus. After 1465 he wrote his chief work, a commentary on the Four Books of Sententiae 'Sentences'. He died at Rome in 1475 and was interred in the church of the Ara Coeli on the Capitoline. Under the entry for the word Dorbel, the Oxford English Dictionary gives the date of his death as 1455. The meaning of Dorbel (based on the name of Nicholas de Orbellis) is given as: a scholastical pedant, a dull-witted person, dolt.
