In the same manuscript with Daniel’s treatise is a work by another Englishman, Roger of Hereford,[522] who was contemporary with him, who wrote treatises both in astronomy and astrology, and who, again like Daniel, was encouraged by a bishop. We are not, I believe, directly informed whether any of his works were translations from the Arabic or whether he was ever in Spain, but some of them sound as if they might be at least adaptations from the Arabic. At any rate Alfred of England dedicated to Roger the translation which he made from the Arabic of the pseudo-Aristotelian _De vegetabilibus_. Astronomical tables which Roger calculated for the meridian of Hereford in 1178 are based upon tables for Marseilles and Toledo, and the manuscript of one of his works is said by the copyist of 1476 to have been taken by him from an ancient codex written in Toledo in the year 1247.[523] Other astronomical treatises attributed to Roger are a _Theory of the Planets, a Treatise concerning the rising and setting of the Signs_, and a _Compotus_ which dates itself in 1176 and is addressed to a Gilbert[524] who seems to be no other than Foliot, bishop of Hereford until 1163 and thereafter bishop of London. The signature of Roger of Hereford attests one of his documents in 1173-1174. In 1176 in the preface to the _Compotus_[525] Roger speaks of himself as _iuvenis_, and the heading in the manuscript even calls him “Child Roger” or “Roger Child,”[526] but he also says that he has devoted many years to learning, so that we need not regard him as especially youthful at that time. The definite dates in his career seem to fall in the decade from 1170 to 1180, although his association with Alfred of England may well have been later. [Sidenote: An astrology in four parts.]
