The usual names of these twelve were—Jupiter, Neptune, Juno, Latona, Apollo, Diana, Pallas, Venus, Vulcan, Mercury, Vesta, and Ceres; but there were multitudes besides—“gods many and lords many” of all sorts of different dignities.  Every river had its god, every mountain and wood was full of nymphs, and there was a great god of all nature called Pan, which in Greek means All.  Neptune was only a visitor in Olympus, though he had a right there.  His kingdom was the sea, which he ruled with his trident, and where he had a whole world of lesser gods and nymphs, tritons and sea horses, to attend upon his chariot.
