=Hebe= in Olympos performs somewhat similar functions to Iris, more particularly that of pouring out wine for the gods.[930] She is also specially associated with Herakles at and after his apotheosis,[931] appearing as his bride in several instances.[932] Besides these, she frequently appears in assemblies of the gods,[933] or at the punishment of Marsyas,[934] or the Judgment of Paris.[935] § 4. PERSONIFICATIONS The next group of deities with which we have to deal is that of the various personifications which are to be found in great numbers on vases of all periods, especially the later. These naturally fall under several headings, which, following the lines of the classification adopted by M. Pottier in a valuable article on the subject,[936] we may distribute as follows:— 1. Physical (Sun, Moon, Dawn, Winds, etc.). 2. Geographical (Cities, Rivers, Mountains, etc.). 3. Products of earth (Wine, Harvest, etc.). 4. Groups of various kinds (Muses, Nymphs, etc.). 5. Physical conditions (Health, Old Age, etc.). 6. Social advantages (Wealth, Peace, Victory, etc.). 7. Ethical ideas (Justice, Envy, Strife, etc.). 8. Metaphysical ideas (Necessity, Law, etc.). 9. Social enjoyments (Comedy, Tragedy, Revelry, etc.). 10. Descriptive names. Of some of these, indeed, we have already treated—such as the beings included in the following of Aphrodite and Dionysos, Ge-Pandora, Hebe (Youth), and the deities of the nether world. The rest we now proceed to consider in order, beginning with natural phenomena, and firstly those of an astronomical character.
