BACCHI, in Mechanics, a kind of ancient ma-
chines, in form of goats, used by Jupiter, in his wars
against the giants. Rudbeck describes two kinds of
bacchi, one made like the battering-ram, wherewith
Jupiter demolished the enemy's fortifications; the
other contrived to cast fire out of, from whence the
Greeks are conjectured to have framed their idea of
the chimera.
