Cellarius, Martinus (Surnamed Borrhaeus),
was born at Stuttgardt in 1499; studied at Tubingen, and afterwards at Wittenberg (under Melancthon), where he devoted himself to Oriental languages. When the Anabaptists arose, he wrote and spoke against them, especially against Stock; but finally he joined them himself. About 1530 he gave up this enthusiasm and went to Basle, assuming the name of Borrhaeus. He became professor of rhetoric there in 1536; of theology, 1544; and died Oct. 11, 1564. — Melchior, Adam, Vit. Eruditorum; Herzog, Real-Encyklop. s.v.
