Mars is said to have begotten Meleager upon Althaea.—Euripides, in his Meleager.
Septimius Marcellus took to wife one Sylvia, and a great
lover of hunting he was. Mars put himself in the habit
of a shepherd, whored the new wife and got her with
child; which being done, he told her who he was, and
gave her a spear, telling her that the fate of the child
she went withal was wrapped up in the fate of that
spear. . . .
Septimius slew Tuscinus; but Mamercus, in his sacrificing to the Gods for a fruitful season, omitted only Ceres,
who in revenge sent a wild boar into his grounds. Whereupon getting a knot of huntsmen together, he killed him,
and delivered the head and skin to his sweetheart; but
Scymbrates and Muthias, the maid's uncles, took them
away from her. Mamercus in a rage killed them upon it,
and the mother burned the spear.—Menyllus, in the Third
Book of his Italian History.
