a more-than-lifesized scallop shell. The Italian Renaissance painter Sandro Botticelli used the type in his The Birth of Venus. Other versions of Venus' birth show her standing on land or shoreline, wringing the sea-water from her hair. Venus Barbata ("Bearded Venus"), mentioned in Servius' commentary on Virgil's Aeneid. Macrobius's Saturnalia describes a statue of Venus in Cyprus, bearded, with male genitalia but in female attire and figure (see also Aphroditus). Her worshippers cross-dressed - men wore women's clothes, and women wore men's. Macrobius says that Aristophanes called this figure Aphroditos. The Latin poet Laevius wrote of worshipping "nurturing Venus" whether female or male (sive femina sive mas). Several examples of Greek and Roman sculpture show her in the attitude anasyrmene, from the Greek verb anasyromai, "to pull up one's clothes" to reveal her male genitalia. The gesture traditionally held apotropaic or magical power. Venus Caelestis (Celestial or Heavenly Venus), used from the 2nd century AD for Venus as an aspect of a syncretised supreme goddess. Venus Caelestis is the earliest known Roman recipient of a taurobolium (a form of bull sacrifice), performed at her shrine in Pozzuoli on 5 October 134. This form of the goddess, and the taurobolium, are associated with the "Syrian Goddess", understood as a late equivalent to Astarte, or the Roman Magna Mater, the latter being another supposedly Trojan "Mother of the Romans", as well as "Mother of the Gods". Venus Calva ("Venus the bald one"), a legendary form of Venus, attested only by post-Classical Roman writings which offer several traditions to explain this appearance and epithet. In one, it commemorates the virtuous offer by Roman matrons of their own hair to make bowstrings during a siege of Rome. In another, king Ancus Marcius' wife and other Roman women lost their hair during an epidemic; in hope of its restoration, unafflicted women sacrificed their own hair to Venus. Venus Cloacina ("Venus the Purifier"); a fusion of Venus with the Etruscan water goddess Cloacina, who had an ancient shrine above the outfall of the Cloaca Maxima, originally a stream, later covered over to function as Rome's main sewer. The rites conducted at the shrine were probably meant to purify the culvert's polluted waters and noxious airs. Pliny the Elder, remarking Venus as a goddess of union and reconciliation, identifies the shrine with a legendary episode in Rome's earliest history, in which the Romans, led by Romulus, and
