=254.= According to this system Juppiter becomes the fiery heaven, the chief of the elements, the source of all life[80]; Juno is the softer air, into which the fire enters to become the germinating seed[81]. Thus she is called sister as a fellow-element[82], and wife as an instrument in the creative process. From a slightly different point of view Chrysippus interpreted Zeus as God, and Hera as matter; and their union as the commencement of the Creation, when God spread throughout matter the seed Logoi[83]. So again Hephaestus (Vulcan) represents fire; Poseidon (Neptune) is the sea; Dis (Pluto) and Rhea alike stand for the earth[84]. Demeter (Ceres) again is the corn-land[85], and Persephone (Proserpine) the growing crop; as such she is lost to her mother and lamented by her for six months in every year[86]. Apollo is the sun, Luna or Diana the moon[87]; Cronus, son of Earth and Heaven, is Chronos (χρόνος) or Time, and he is said to devour his children, because all that is begotten of time is in turn consumed by time[88]. Athene or Minerva is the daughter of Zeus, to whom he has given birth without a partner, because she is the divine Reason by which he made the universe[89]. Chrysippus wrote at length on the allegorical interpretation of the three Graces[90]; and the work of Cornutus entirely consists of expositions of this system. Other gods are recognised by the Stoics as personifications of actions or feelings; Eros (Cupid), Aphrodite (Venus) and Pothos (regret) of feelings; Hope (Ἐλπίς, _Spes_), Justice (Δίκη, _Iustitia_) and Wise Law (Εὐνομία) of actions[91]. So in particular Ares (Mars) stands for war, or the setting of array against array. [Sidenote: Minor deities.]
