To knowe the degrees of longitudes of fixe sterres after that they be determynat in thin Astrelabye, yf so be that thei be trewly sette.

Set the centre of the sterre upon the lyne meridionall, and tak kep of thy zodiak, and loke what degre of eny signe that sitte upon the same lyne meridionall at that same tyme, and tak there the degre in which the sterre stondith; and with that same degre cometh that same sterre unto that same lyne fro the orisonte.
