Ithyphallic

A phallus is a penis, especially when erect, an object that resembles a penis, or a mimetic image of an erect penis.

Any object that symbolically—or, more precisely, iconically—resembles a penis may also be referred to as a phallus; however, such objects are more often referred to as being phallic (as in "phallic symbol"). Such symbols often represent fertility and cultural implications that are associated with the male sexual organ, as well as the male orgasm.

The term is a loanword from Latin phallus, itself borrowed from Greek φαλλός, which is ultimately a derivation from the Proto-Indo-European root *bʰel- "to inflate, swell". Compare with Old Norse (and modern Icelandic) boli "bull", Old English bulluc "bullock", Greek φαλλή "whale".

The Hohle phallus, a 28,000-year-old siltstone phallus discovered in the Hohle Fels cave and first assembled in 2005, is among the oldest phallic representations known.

In traditional Greek mythology, Hermes, god of boundaries and exchange (popularly the messenger god) is considered to be a phallic deity by association with representations of him on herms (pillars) featuring a phallus. There is no scholarly consensus on this depiction and it would be speculation to consider Hermes a type of fertility god. Pan, son of Hermes, was often depicted as having an exaggerated erect phallus.

Priapus is a Greek god of fertility whose symbol was an exaggerated phallus. The son of Aphrodite and either Dionysus or Adonis, according to different forms of the original myth, he is the protector of livestock, fruit plants, gardens, and male genitalia. His name is the origin of the medical term priapism.
