ARACH'NE. A particular kind of sun-dial, which is naturally believed to have received its name from a resemblance to the spider's web produced by the hour lines intersecting the circles of the equator and tropics, described upon it; but of which no ancient specimen has been discovered. Vitruv. ix. 8.
