Text name The Equatorie of the Planets File name cmequato-m3 Manuscript Peterhouse 75.1, Cambridge Date c1392 Dialect East Midlands Genre Handbook, astronomy Edition Price, Derek J. 1955. The equatorie of the planetis. Cambridge: Cambridge University Press. Sample Pp. 18.1-44.39 Remarks
This treatise describes the construction and use of an instrument called an equatorium planetarum, which was used for calculating the positions of the planets. It is derived from a Latin version of an unknown Arabic treatise. The Latin treatise may have been written by Simon Bredon, an astronomer at Merton College who died in 1372. Price ascribes the work to Chaucer and gives evidence that it is a Chaucer holograph, although as he notes the evidence is not conclusive. Robinson, editor of The Works of Geoffrey Chaucer, was not convinced and did not include The Equatorie in his collection. Further evidence bearing on Chaucerian authorship has not been forthcoming. If not written by Chaucer, the treastise was written by a contemporary Londoner (Benson, p. xxvii).
