The Late Babylonian tablet BM 92687 preserves a unique Babylonian birds-eye-view sketch of the Earth's surface. The sketch, commonly called “The Babylonian Map of the World” or “Mappa Mundi”, occupies the lower half of the obverse while the remainder of the obverse and entire reverse préserve related textual information. The tablet was first published almost a century ago by F. E. Peiser in ZA 4 (1889), 361–370, and has since attracted a great deal of attention. In 1906, R. C. Thompson re-copied the tablet as CT 22, 48. This second copy served as the basis for later studies by E. F. Weidner in BoSt 6 (1922), 85–93 and E. Unger in Unger, Babylon, 254–8 (1931). Unfortunately, neither the early copy by Peiser, nor CT 22, 48, is completely reliable. The two copies disagree on a number of points, and a new collation of the tablet revealed a number of errors. For instance, Peiser drew two nagû at the bottom of the map which are omitted in CT 22, 48, and both copyists read the label in the lowest oval inside the circle (no. 8) sideways! Thus a new copy and edition of the text is warranted although a few signs may have disappeared over time. (Copy: see Fig. 2 p. 152; photographs, Plate X).
