    • n Colure (Astron. & Geog) 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 90° 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 ."
