The ancients were fond of finding a hidden meaning in their mythological tales. They explain this fight of Achelous with Hercules by saying Achelous was a river that in seasons of rain overflowed its banks. When the fable says that Achelous loved Dejanira, and sought a union with her, the meaning is that the river in its windings flowed through part of Dejanira’s kingdom. It was said to take the form of a snake because of its winding, and of a bull because it made a brawling or roaring in its course. When the river swelled, it made itself another channel. Thus its head was horned. Hercules prevented the return of these periodical overflows by embankments and canals; and therefore he was said to have vanquished the river-god and cut off his horn. Finally, the lands formerly subject to overflow, but now redeemed, became very fertile, and this is meant by the horn of plenty. There is another account of the origin of the Cornucopia. Jupiter at his birth was committed by his mother Rhea to the care of the daughters of Melisseus, a Cretan king. They fed the infant deity with the milk of the goat Amalthea. Jupiter broke off one of the horns of the goat and gave it to his nurses, and endowed it with the wonderful power of becoming filled with whatever the possessor might wish. The name of Amalthea is also given by some writers to the mother of Bacchus. It is thus used by Milton, “Paradise Lost,” Book IV.: “. . . That Nyseian isle, Girt with the river Triton, where old Cham, Whom Gentiles Ammon call, and Libyan Jove, Hid Amalthea and her florid son, Young Bacchus, from his stepdame Rhea’s eye.” ADMETUS AND ALCESTIS Æsculapius, the son of Apollo, was endowed by his father with such skill in the healing art that he even restored the dead to life. At this Pluto took alarm, and prevailed on Jupiter to launch a thunderbolt at Æsculapius. Apollo was indignant at the destruction of his son, and wreaked his vengeance on the innocent workmen who had made the thunderbolt. These were the Cyclopes, who have their workshop under Mount Ætna, from which the smoke and flames of their furnaces are constantly issuing. Apollo shot his arrows at the Cyclopes, which so incensed Jupiter that he condemned him as a punishment to become the servant of a mortal for the space of one year. Accordingly Apollo went into the service of Admetus, king of Thessaly, and pastured his flocks for him on the verdant banks of the river Amphrysos.
