 Zod. 1846, p. 15. Ideler and Lepsius also consider it probable that " the 

 knowledge of the Chaldean zodiac, both as respects the division and the 

 name, had reached the Greeks as early as the 7th century before our era, but 

 that the reception of the several zodiacal figures into the Grecian astronomi- 

 cal literature was later, and only followed gradually" (Lepsius, Chronologic 

 der ^Bgypter, 1849, S. 65 and 124). Ideler is inclined to believe that the 

 Orientals had for their twelve divisions (Dodecatomery) names, but without 

 figures ; Lepsius thinks it natural to suppose " that the Greeks, at a time 

 when their sphere was in great part unoccupied, would add to their own 

 the Chaldean constellations from which the twelve divisions were named." 

 But, on this supposition, might we not ask why the Greeks should have had 

 at first only eleven signs, and not all the twelve signs of the Chaldean 

 Dodecatomery ? If they had received twelve figures, they would surely not 

 have cut out one to replace it subsequently.

 transcriber as if belonging to Hipparchus, see Letronne, Orig. du Zod. 1840, 

 p. 20. As early as 1812, when I was myself still inclined to suppose that 

 the Greeks had been very early acquainted with the sign of the Balance, I 

 pointed out, in a carefully written memoir on the passages from Greek and
