Note 412 — Chapter IV · THE SOURCES FOR THE PERIOD 1100–1250 A. D.

Steinschneider, Études sur Zarkali, 1881–1887, discusses the various versions of Az-Zarqalī’s Canons and of the Toledo Tables. The former were put into Hebrew, Spanish, Italian, and Latin; of the Latin versions, 400the manuscripts are more numerous in England than elsewhere, but there are no fewer than nine in the Bibliothèque Nationale in Paris. The Toledo Tables probably did not become well known in the Latin West until the first half of the thirteenth century (see Duhem, Système, vol. iii, 1915, pp. 287–290), although they were probably known to Roger of Hereford (see Haskins, Reception, 1915, p. 66; the same, Studies, 1924, p. 95; and Duhem, op. cit., pp. 520–521).
