Note 456 — Chapter IV · THE SOURCES FOR THE PERIOD 1100–1250 A. D.

C. V. Langlois, La connaissance, 1911, pp. 49–113. On the sources of the Image du monde, see the works of Fant, Fritsche, and Le Clerc, referred to in the Bibliography under these names. The poem in the first redaction was divided into three main parts: first, the part dealing with cosmogony, in fourteen chapters; second, that dealing with geography, in eighteen chapters; third, that dealing with astronomy, in twenty-two chapters. The second part, on geography, follows the De imagine mundi very closely, with additions from Jacques de Vitry. Fritsche, Untersuchung, 1880, gives an analysis of the work chapter by chapter. The “mediocrity” of Fritsche’s book, which Langlois asserts, is illustrated by its author’s inability to identify the city of “Aaron”—obviously the world center, Arin (Fritsche, op. cit., p. 23).
