The socle often has an image of Tyche on it. He usually wears a gown with a variety of astral symbols on it. Sometimes these are merely disks or rosettes, but often they are busts of Helios and Selene or of all seven planet-gods, identified by their usual attributes. In two examples, twelve busts for the twelve signs of the zodiac occur. In another example, a statue of Jupiter Heliopolitanus from Sohne, near Palmyra, has the Bel triad on its chest.
Many examples have an eagle with wings outspread on the back.
The image of Tyche on a socle says the same thing. Tyche here is a personification of heimarmene, the power of the planets to compel. And, as elsewhere, the eagle was used to symbolize the sky-god, spread out over the earth. The fact that this iconography is found on dedications and ex votos implies that the ideas that it symbolized were common, well-known to worshippers. Thereafter, the snakelike body transformed itself into a great star.
