(Astron. & Geog.)
Definition: One of two great circles intersecting at right angles in the
poles of the equator. One of them passes through the equinoctial
points, and hence is denominated the equinoctial colure; the other
intersects the equator at the distance of 90Âş from the former, and is
called the solstitial colure.
Thrice the equinoctial line He circled; four times crossed the car of
night From pole to pole, traversing each colure. Milton.
