The ordinary symbol of germination, a median projection with lateral
extensions at the base (plate CXLIX, _e_), occurs among the figures on
this ancient pottery. In its simplest form, a median line with a
triangle on each side attached to one end, it is a phallic emblem.
When this median line becomes oval, and the triangles elongated and
curved at the ends, it represents the ordinary squash symbol,[152]
also used as an emblem of fertility.
The triangle is also an emblem of germination and of fecundity--the
female, as the previously mentioned principle represents the male. The
geometric designs on the ancient Sikyatki ware abundantly illustrate
both these forms.
