The Hindu-Arabic Numerals c12.87

c12.87

As to monumental inscriptions,³ there was once thought to be a gravestone at Katharein, near Troppau, with the date 1007, and one at Biebrich of 1299. There is no doubt, however, of one at Pforzheim of 1371 and one at Ulm of 1388.⁴ Certain numerals on Wells Cathedral have been assigned to the thirteenth century, but they are undoubtedly considerably later.⁵
