myths, the Chaldæans had a vast number of so-called heroic and nature myths. The most noted of these form what is known as the Epic of Izdubar (Nimrod?), which is doubtless the oldest epic of the race. This is in twelve parts, and is really a solar myth, which recounts the twelve labors of the sun in his yearly passage through the twelve signs of the Chaldæan zodiac. This epic was carried to the West, by the way of Phœnicia and Asia Minor, and played a great part in the mythology of the Greeks and Romans. "The twelve labors of Heracles may be traced back to the adventures of Gisdhubar [Izdubar] as recorded in the twelve books of the great epic of Chaldæa." (Sayce.)
Science.—In astronomy and arithmetic the Chaldæans made substantial progress. The clear sky and unbroken horizon of the Chaldæan plains, lending an unusually brilliant aspect to the heavens, naturally led the Chaldæans to the study of the stars. They early divided the zodiac into twelve signs, and named the zodiacal constellations, a memorial of their astronomical attainments which will remain forever inscribed upon the great circle of the heavens; they foretold eclipses, constructed sun-dials of various patterns, divided the year into twelve months, and the day and night into twelve hours each, and invented or devised the week of seven days, the number of days in the week being determined by the course of the moon. "The 7th, 14th, 19th, 21st, and 28th days of the lunar month were kept like the Jewish Sabbath, and were actually so named in Assyria."
In arithmetic, also, the Chaldæans made considerable advance. A tablet has been found which contains the squares and cubes of the numbers from one to sixty.
Conclusion.—This hasty glance at the beginnings of civilization among the primitive peoples of the Euphrates valley, will serve to give us at least some little idea of how much modern culture owes to the old Chaldæans. We may say that Chaldæa was one of the main sources—Egypt was the other—of the stream of universal history.
