“The 27th day the moon disappeared; the 28th 29th and 30th day we continually observed the node of the obscuring sun. The eclipse did not take place. The 1st day (of the following month) we saw the moon during the first day of the month Tammuz (June) above the star Mercury of which I have previously sent an observation to the king my master. In its course during the day of Anu, around the shepherd star (the planet Venus), it was seen declining: on account of rain the horns were not very distinctly visible, and so it was in its whole course. The day Anu I sent the observation of its conjunction, to the king my master. It was prolonged and was visible above the star of the Chariot in its course during the day of Baal; it disappeared towards the star of the Chariot.
“To the King, my Lord, peace and happiness.”
The discovery of the precession of the equinoxes is generally attributed to Hipparchus. It was he, indeed, who taught this fact to the Greeks, and he estimated its yearly amount as from 36 to 39 seconds; but it is certain that he learned about it in Chaldea, and that he obtained the elements of his calculations from the astronomical observations made on the lower Euphrates. All the astronomical knowledge of the Ninevite savants had the same point of origin.
Two thousand years before our era, from the time of a king of Agade called Sharrukin (Shargani-shar-ali), and who is usually known as Sargon I (the Ancient), the precession of the equinoxes was an observed and calculated fact, since it had already brought sufficient disturbance into the calendar to make a corrective element necessary. Sargon had given a brilliancy to his century which the learned men of Nineveh only echoed. In his time there was a library at Agade, the importance of which we can judge by the fragments which were preserved at Nineveh. We are certain that at these remote times the great divisions of the uranographic chart were already determined upon. Fixed stars were designated according to the different groups or constellations which were known by the names they have retained to this day.
Outside these fixed stars the signs of the zodiac were perfectly determined in that portion of the celestial vault which the texts designate by the name of harranu (the way), that is to say, the way of the stars. These stars were the planets. The Chaldeans knew of seven, and they were thus known to them: Shamash, the sun; Sin, the moon; Alap-Shamash, Saturn; Rus, Jupiter; Ashbat, Venus; Sulpa-sadu, Mars; Nivit-Anu, Mercury. The Ninevite savants borrowed their astronomical knowledge from the Chaldeans; they made use of the calendar as it was transmitted to them, and as such it has been used by all nations from the remotest times up to the present day.
The Assyrian year was composed of twelve lunar months. It began with the new moon preceding the vernal equinox. A well-known tablet thus fixes the day of the equinoxes: “At the sixth day of the month of Nisan (March) the days and nights are equal (and comprise), six kashbu for the day and six kashbu for the night. May Nabu and Marduk be propitious to the King, my Lord.”
To correct the error resulting from the difference between the lunar and solar year, a supplementary month was intercalated, the length of which necessarily varied with circumstances. The Ninevite tablets offer us calendars arranged in conformity with the different exigencies of life. Some are purely scientific, and show us the divisions of the year into days, months, and seasons. Others are formed to meet the needs of religion, and tell us, by the day, the feasts consecrated to divinities invoked or honoured by special ceremonies. Others seem to take current superstitions into account; thus days are marked by a particular sign, according as they are considered propitious or disastrous. We see tables constructed to indicate the influence of the stars on each day of the year, with a mention of appropriate prayers, to propitiate favourable auguries and ward off those which are fatal.
The importance of these last documents must not be exaggerated; they are related to superstitions common to all ages and lands; and, in the ancient East, as everywhere else, these beliefs merely represent one of the most curious, but the least interesting phases of the aberrations of the human mind.
