phaeton

A hypothetical planet between Mars and Jupiter that was suggested by Heinrich Wilhelm Matthäus Olbers. He supposed that the planet's destruction formed the Asteroid Belt. Some scientists refer to this proposed planet as Tiamat. (Wikipedia)

Then there's the recently discovered ancient parchment -
"Pythons on a Phaeton" (said to have been a particular favorite of the Gorgon set).

The name phaeton derives from a Greek mythological character, Phaethon, who almost set the world on fire with his reckless driving. This type of carriage was made of wicker, making it quite lightweight. The Phaeton was intended for pleasure driving.

He drove a great roomy, double "phaeton" drawn by two satin bay horses.
_From Pat of Silver Bush by L.M. Montgomery, 1933

Four people, each with his or her own folding top. On his or her head.

See also phaethon.

Wait... does the WeirdNet definition mean that it seats four (presumably people) who have folding tops? Or four people who have one folding top between them?
