- n. The ascending node of a planet, indicated, chiefly in almanacs, by the symbol �. The deviation from the ecliptic made by a planet in passing from one node to the other seems, according to the fancy of some, to make a figure like that of a dragon, whose belly is where there is the greatest latitude; the intersections representing the head and tail; -- from which resemblance the denomination arises.
