The conduct of the king was of special significance at periods when for some reason or other, the gods were not favorably disposed. Partly on the basis of actual observation that eclipses (which were especially feared) had occurred on certain days of the month, partly as a consequence of the belief that the change in the moon's phase augured something good or evil for humanity, and in part perhaps through the coincidence that on a certain day of the month, mishaps of some kind had occurred several times, certain months and certain days of each month were regarded as favorable, while others were unfavorable. Some months and some days were suitable for dedicating a building, others were not. On some days an oracle might be sought, on others not. Some days were days of rejoicing, on others again mourning was appropriate. Advantage had to be taken of the favorable days to keep the deity in good humor, and it was equally important on the unfavorable ones to exercise great care not to do aught which might arouse the anger of a god, ready to be incensed. It is the king who can best accomplish the one thing and avoid the other. To him, as standing nearer the deity than any private individual, the country looked for safety and protection. Calendars were prepared for each month of the year, in which the peculiar character of each day was noted and instructions added what was to be done on each day. These instructions all have reference to the king and to the king alone. A complete calendar for the intercalated month of Elul has been preserved.[608] It may serve as an example of the branch of the omen literature to which it belongs. The thirty days of each month are taken up in succession. The deity to which each day is sacred is indicated, and various sacrifices or precautions prescribed. A curious feature of this calendar was that, since it was the hope to make every day 'favorable,' each day was called so, even when it is evident that it was not. For the 1st day of Elul the second,[609] sacred to Anu and Bel, a favorable day. When the moon makes its appearance in this month, the king of many peoples brings his gift, a gazelle together with fruit, ... his gift to Shamash, lord of the countries, and to Sin, the great god, he gives. Sacrifices he offers, and his prayer to his god[610] is acceptable. On the 2d day sacred to goddesses, a favorable day. The king brings his gift to Shamash, the lord[611] of countries. To Sin, the great god, he offers sacrifices. His prayer to the god is acceptable. On the 3d day, a day of supplication to Marduk and Sarpanitum, a favorable day. At night, in the presence of Marduk and Ishtar,[612] the king brings his gift. Sacrifices he is to offer so that his prayer may be acceptable.
