The Catalan Atlas is conventionally attributed to 1375, because that year is used as the starting-point for the computation of the Golden Number, but 1376 and 1377 are also mentioned in its accompanying texts; it conforms closely to the description of such an atlas in the French royal library catalogue, dated 1380 [...] The Catalan Atlas can be assigned with some confidence to the late 1370s or the early 1380s.
