The mystic identifications do not always agree, but the term of comparison can generally be found if the origin and character of the deities are known and the nature of the symbol determined. Each god was associated with an animal and a plant and with other forms of nature over which they presided. When the cult utensils are symbols the term of comparison is generally clear. Below will be found such interpretations of these mysteries as the condition of the tablet and the limits of our knowledge permit. Most difficult of all are the metal symbols which begin with Obv. I 10. Here silver is heaven, but it can hardly be explained after the manner of the same connection of Zeus Dolichaîos with silver in Kommagene. The cult of this Asiatic heaven god is said to have been chiefly practiced at a city in the region of silver mines.(519) That is an impossible explanation in the case of Anu whose chief cult center was at Erech. The association of gold with Enmesharra, here obviously the earth god, is completely unintelligible. In Obv. I 31 he is possibly associated with lead or copper as the planet Saturn. In lines I 14-18 the symbols are broken away, but they are probably based upon astronomy. Metals seem to be connected with fixed stars and planets on the principle of color. The metallic symbolism of the planets was well known to Byzantine writers who did not always agree in these matters. Their identifications are certainly a Græco-Roman heritage which in turn repose upon Babylonian tradition.(520) The following table taken from COOK, _Zeus_, p. 626, will illustrate Græco-Roman ideas on this point: Kronos—lead (Saturn); Zeus—silver (Jupiter); Ares—iron (Mars); Helios—gold (Sun); Aphrodite—tin (Venus); Hermes—bronze (Mercury); Selene—crystal (Moon). Our tablet preserves only the names of the deities at this point, and if metals stood at the left we are clearly authorized to interpret the divine names in their astral sense. This assumes, of course, that these astral identifications obtained in the Cassite period. Assuming this hypothesis we should have the metals for Betelgeuze, Ursa Major, Venus, Jupiter, Mars, Saturn, New-moon(?), a star in Orion, Venus as evening and morning star, Virgo, and perhaps others.
