Priapus

Priapus is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Priapus rather than just read about it. In short: In Greek mythology, Priapus (; Ancient Greek: Πρίαπος, romanized: Príapos) is a minor rustic fertility god, protector of livestock, fruit plants, gardens, and male genitalia. Priapus is marked by his oversized penis, and his permanent erection, which gave rise to the medical term priapism.

Key takeaways

  • Priapus belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Priapus to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Priapus from memory before moving on to harder problems.

Reference excerpt

In Greek mythology, Priapus (; Ancient Greek: Πρίαπος, romanized: Príapos) is a minor rustic fertility god, protector of livestock, fruit plants, gardens, and male genitalia. Priapus is marked by his oversized penis, and his permanent erection, which gave rise to the medical term priapism. He became a popular figure in Roman erotic art and Latin literature, and is the subject of the often humorously obscene collection of verse called the Priapeia.

Mythology

Relationship with other deities Priapus was described in varying sources as the son of Aphrodite by Dionysus; as the son of Dionysus and Chione; as perhaps the father or son of Hermes; or as the son of Zeus or Pan. According to legend, Hera cursed him with inconvenient impotence (he could not sustain an erection when the time came for sexual intercourse), ugliness and foul-mindedness while he was still in Aphrodite's womb, in revenge for the hero Paris having the temerity to judge Aphrodite more beautiful than her. In another account, Hera's anger and curse were because the baby had been fathered by her husband Zeus. The other gods refused to allow him to live on Mount Olympus and threw him down to Earth, leaving him on a hillside. He was eventually found by shepherds and was brought up by them. Priapus joined Pan and the satyrs as a spirit of fertility and growth, though he was perennially frustrated by his impotence. In a ribald anecdote told by Ovid, he attempted to rape the goddess Hestia but was thwarted by an ass, whose braying caused him to lose his erection at the critical moment and woke Hestia. The episode gave him a lasting hatred of asses and a willingness to see them killed in his honour. The emblem of his lustful nature was his permanent erection and his large penis. Another myth states that he pursued the nymph Lotis until the gods took pity on her and turned her into a lotus plant. "Priapos" is a title given to Eros Phanes in the Orphic Hymn to Protogonos, the "firstborn" god of the Greeks who came from the Cosmic Egg. In The Orphic Hymn to Dionysus, Dionysus is given epithets similar to Protogonos and was thought of as the incarnation of Protogonos, so he was considered both the father of fertility god Priapus and also the incarnation of the primordial Priapus.

Other works As well as the collection known as the Priapeia mentioned above, Priapus was a frequent figure in Latin erotic or mythological verse. In Ovid's Fasti, the nymph Lotis fell into a drunken slumber at a feast, and Priapus seized this opportunity to advance upon her. With stealth he approached, and just before he could embrace her, Silenus's donkey alerted the party with "raucous braying". Lotis awoke and pushed Priapus away, but her only true escape was to be transformed into the lotus tree. To punish the donkey for spoiling his opportunity, Priapus bludgeoned it to death with his gargantuan phallus. When the same story is recounted later in the same book, Lotis is replaced with the virginal goddess Hestia, who avoids being changed into a tree as the other Olympians come to her rescue. Ovid's anecdote served to explain why donkeys were sacrificed to Priapus in the city of Lampsacus on the Hellespont, where he was worshipped among the offspring of Hermes. Once, a donkey that had been given human speech by Dionysus challenged Priapus to a contest about which between them had the better penis. Priapus won the contest, and then killed the donkey, which was put by Dionysus among the stars. In Lucian's Dialogues of the Gods, Priapus conceives a desire for the sleeping Dionysus and attempts to assault him, but the attempt is thwarted when Dionysus wakes up.

Worship and attributes

The first extant mention of Priapus is in the eponymous comedy Priapus, written in the 4th century BC by Xenarchus. Originally worshipped by Greek colonists in Lampsacus in Asia Minor, the cult of Priapus spread to mainland Greece and eventually to Italy during the 3rd century BC. Lucian (De saltatione) tells that in Bithynia Priapus was accounted as a warlike god, a rustic tutor to the infant Ares, "who taught him dancing first and war only afterwards," Karl Kerenyi observed. Arnobius is aware of the importance accorded Priapus in this region near the Hellespont. Also, Pausanias notes:

This god is worshipped where goats and sheep pasture or there are swarms of bees; but by the people of Lampsacus he is more revered than any other god, being called by them a son of Dionysus and Aphrodite. In later antiquity, his worship meant little more than a cult of sophisticated pornography. Outside his "home" region in Asia Minor, Priapus was regarded as something of a joke by urban dwellers. However, he played a more important role in the countryside, where he was seen as a guardian deity. He was regarded as the patron god of sailors and fishermen and others in need of good luck, and his presence was believed to avert the evil eye. Priapus does not appear to have had an organized cult and was mostly worshiped in gardens or homes, though there are attestations of temples dedicated to the god. His sacrificial animal was the ass, but agricultural offerings (such as fruit, flowers, vegetables and fish) were also very common. Long after the fall of Rome and the rise of Christianity, Priapus continued to be invoked as a symbol of health and fertility. The 13th-century Lanercost Chronicle, a history of northern England and Scotland, records a "lay Cistercian brother" erecting a statue of Priapus (simulacrum Priapi statuere) in an attempt to end an outbreak of cattle disease. In the 1980s, D. F. Cassidy founded the St. Priapus Church as a modern church centred on worship of the phallus.

Worked examples

Example 1 — a first encounter with Priapus

Start with the simplest possible case. Write down what Priapus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Priapus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Priapus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Priapus

In research
Priapus appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Priapus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Priapus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural deities, Agricultural gods, Children of Aphrodite, so understanding it makes those chapters shorter.
In everyday life
Look for Priapus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
