Eagleton further relates the letters of the hour division of the limb to one method of dividing the compass and the visible horizon, citing Chaucer’s reference to “this orisonte departed in 24 partis by this azimutes in signification of the 24 parties of the world”, Eagleton, “‘Chaucer’s Own Astrolabe’” (cit. note 18), p. 320; Chaucer, however, is referring to the horizon line on the latitude projection, which is indeed divided by the azimuths into 24 intervals of 15 degrees, and not to the limb of the mater.
