According to a Babylonian myth, Marduk created the Great Dragon putting its head into the Moon's ascending node and its tail into the descending node, making it carry six of the zodiacal constellations on its back and six under its belly. This is pictorially illustrated on a Babylonian Boundary Stone of King Nabushun-iskun.
This implies that the Babylonians considered that the positions of the planets in the Draconic zodiac" (i.e. distances measured from the Moon's north node) were of consequence. The fact that the mean sidereal longitude of Caput Draconis ("Dragon's Head") was EXACTLY at the beginning of the constellation Aries on 1st Nisan, and thus carrying the first six zodiacal constellations on its back and the second six under its belly, is astonishing; especially when taking into consideration the other remarkable astronomical features of this year. The pre-knowledge of this fact alone may have had no little bearing on the decision to install Nabu in his new temple at Kalakh during the limmu of Balatu. In this respect it should be noted that tradition is in error in giving the exaltation of the north node as Gemini 3 degrees (Lilly: Introduction To Astrology," page 72, Bohn Library). As however, the exaltations of the nodes are not mentioned by Claudius Ptolemy, nor do they figure on the Egyptian zodiacs, it must be assumed that they are of more recent origin. In Hindu astrology, Rahu (north node) is stated to be exalted in Taurus, and Ketu (south node) in Scorpio.
