[GWN7]

"As with other automotive terms, the term derives from horse-drawn carriages. A "spider" was a lighter version of a phaeton, having narrower, spindly wheels and two-seat accommodation. The name implied an extremely rudimentary top mechanism originating from a small two-seat horse-cart with a folding sunshade made of four bows; with its black cloth top and exposed sides for air circulation it resembled an eight-legged spider. This term was subsequently applied to automobiles. "
