Description In the diagram in the top half of the page, the observer's point-of-view is the North Pole. This diagram is similar to the one in the lower part of fol. 6v of this same manuscript, except that it also shows the Riphaean Mountains – a mythical range of peaks thought to mark the boundary between Asia and Europe, and the Arctic and North temperate zones -- represented as seven abstract, colored silhouettes resembling triangular game-pieces. The diagram in the bottom half of the page charts the course of the Moon through the zodiac, correlating the lunar or synodic months and the zodiacal signs. According to the De natura rerum (On the nature of things) of the English scholar, Bede (d. 735 CE), the Moon journeys through the zodiac thirteen times in twelve lunar months; thus, it runs through each zodiacal sign in a little over two days and six hours.
