“ DA COSTA, ISAAK (1798–1860) , Dutch poet and theologian, was born at Amsterdam on the 14th of January 1798. His father was a Jew of Portuguese descent, and claimed kindred with the celebrated Uriel D’Acosta. An early acquaintance with Bilderdijk had a strong influence over the boy both in poetry and in theology. He studied at Amsterdam, and afterwards at Leiden, where he took his doctor’s degree in law in 1818, and in literature in 1821. ”
