Dictionary of National Biography, 1885-1900/Thomas of Newmarket
THOMAS of Newmarket (fl. 1410?), arithmetician, graduated M.A. at Cambridge, and wrote a ‘Commentum in Computum Ecclesiasticum Dionysii’ (Exigui), which is in Digby MS. 81, f. 35, and in Peterhouse MS. 189. His ‘Commentum in Carmen Alexandri de Villa Dei de Algorismo’ is in Digby MS. 81, f. 11. A copy was formerly at Corpus College, Cambridge (Misc. Communications, pt. i. No. 3, Cambridge Antiq. Soc. publications, 4to ser.). The ‘Compotus Manualis’ in Digby MS. 81, f. 8, is perhaps also his, and the treatises ‘de Sphæra’ and ‘de Quadrante’ in the Peterhouse manuscript may be by him. Bale confuses his works with those of Thomas Merke [q. v.], bishop of Carlisle.
