Carmelite theologian and humanist (known also as Arnold van Vaernewijck); b. Ghent, 1445; d. Ghent, April 4, 1499. Bostius, subprior and possibly prior at Ghent, served as a spiritual director to Carmelite nuns. He was greatly influenced by the Carmelite reformer Bl. John soreth (d. 1471). Keenly interested in the humanistic movement, Bostius promoted classical studies within his order and was in contact with such leading humanists as erasmus, Sebastian trithemius, Robert brant, gaguin, and Bl. baptist of mantua. He was a proponent of the Immaculate Conception and wrote about the Virgin Mary's patronage of the Carmelites (De patronatu et patrocinio Virginis Mariae ). Bostius also composed works on the history of his order (De illustribus viris; Speculum historiale; and Breviloquium tripartitum ).
