Word Origin and History for hyades


star cluster in constellation Taurus, late 14c., from Greek Hyades, popularly explained as "rain-bringers" (from hyein "to rain"), because wet weather supposedly began coincidentally with their heliacal rising, but in fact probably from hys "swine" (the popular Latin word for them was Suculae "little pigs"). Grimm ("Teutonic Mythology") lists the Anglo-Saxon glosses of Hyades as Raedgastran, Raedgasnan, Redgaesrum.
