Batecumbe, William

, an eminent mathematician, is supposed by Pits to have flourished about 1420. He studied at Oxford, where he applied himself to natural philosophy in general, but chiefly to the mathematics, in which he made a very great proficiency, as is evident by his writings in that science, which introduced him to the acquaintance and intimacy of the greatest men of his time. It is not known when he died. He wrote, 1. “De Sphcerae concavae fabrica et usu;” which Bale saw in the library of Dr. Robert Recorde, a learned physician. 2. tf De Sphsera solida.“3.” De operatione Astrolabii.“4.” Conclusiones Sophise." 2
