Title: Faunus
Content:  In fable Faunus appears as an old king of Latium, grandson of Saturnus, son of Picus, and father of Latinus by the nymph Marica (who was also sometimes Faunus' mother). After his death he is raised to the position of a tutelary deity of the land, for his many services to agriculture and cattle-breeding. A goddess of like attributes, called Fauna and Fatua, was associated in his worship. She was regarded as his daughter, wife, or sister. The female deity Bona Dea was often equated with Fauna. As Pan was accompanied by the Paniskoi, or little Pans, so the existence of many Fauni was assumed besides the chief Faunus. Fauns are place-spirits (genii) of untamed woodland. Educated, Hellenizing Romans connected their fauns with the Greek satyrs, who were wild and orgiastic drunken followers of Dionysus, with a distinct origin.
Title: Faunus
Content:  In ancient Roman religion and myth, Faunus was the horned god of the forest, plains and fields; when he made cattle fertile he was called Inuus. He came to be equated in literature with the Greek god Pan. Faunus was one of the oldest Roman deities, known as the di indigetes. According to the epic poet Virgil, he was a legendary king of the Latins. His shade was consulted as a goddess of prophecy under the name of Fatuus, with oracles in the sacred grove of Tibur, around the well Albunea, and on the Aventine Hill in ancient Rome itself. Marcus Terentius Varro asserted that the oracular responses were given in Saturnian verse. Faunus revealed the future in dreams and voices that were communicated to those who came to sleep in his precincts, lying on the fleeces of sacrificed lambs. W. Warde Fowler suggested that Faunus is identical with Favonius, one of the Roman wind gods (compare the Anemoi).
Title: Faunus
Content:  Faunus may be of Indo-European origin and related to the Vedic god Rudra. It is believed that he was worshipped by traditional Roman farmers before becoming a nature deity.
Title: Faunus
Content:  The name Faunus is generally thought to stem from Proto-Italic *fawe or *fawono (variant *fawōn(jo)), thus being cognate with Umbrian fons, foner ('merciful'). It may ultimately derive from Proto-Indo-European (PIE) *bʰh₂u-n ('favourable'), which also reflects Old Irish búan ('good, favourable, firm') and Middle Welsh bun ('maiden, sweetheart'). Another theory contends that Faunus is the Latin outcome of PIE *dhau-no- ('the strangler', thus denoting the 'wolf'), a proposition suggested by the fact that the Luperci (from Latin lupus, 'wolf') are commonly associated with the god Faunus.
Title: Faunus
Content:  In Justin's epitome, Faunus is identified with Lupercus ("he who wards off the wolf"), otherwise a priest of Faunus. Livy named Inuus as the god originally worshiped at the Lupercalia, 15 February, when his priests (Luperci) wore goat-skins and hit passers-by with goatskin whips. Two festivals, called Faunalia, were celebrated in his honour—one on 13 February, in the temple of Faunus on the island in the Tiber, the other on 5 December, when the peasants brought him rustic offerings and amused themselves with dancing. A euhemeristic account made Faunus a Latin king, son of Picus and Canens. He was then revered as the god Fatuus after his death, worshipped in a sacred forest outside what is now Tivoli, but had been known since Etruscan times as Tibur, the seat of the Tiburtine Sibyl. His numinous presence was recognized by wolf skins, with wreaths and goblets. In Nonnos' Dionysiaca, Faunus/Phaunos accompanied Dionysus when the god campaigned in India.
Title: Fauna (deity)
Content:  The name Fauna is a feminine form of Latin Faunus, the deity of the countryside. Faunus itself is generally thought to stem from Proto-Italic *fawe or *fawono, ultimately from Proto-Indo-European *bʰh₂u-n ('favourable'). Consequently, Georges Dumézil translated her name as "the Favourable." In his conceptual approach to Roman deity, Michael Lipka sees Faunus and Fauna as an example of a characteristically Roman tendency to form gender-complementary pairs within a sphere of functionality. The male-female figures never have equal prominence, and one partner (not always the female) seems to have been modelled on the other. An Oscan dedication naming Fatuveís (= Fatui, genitive singular), found at Aeclanum in Irpinia, indicates that the concept is Italic. Fauna has also been dismissed as merely "an artificial construction of scholarly casuistics."
Title: Fauna (deity)
Content:  Fauna is a Roman rustic goddess said in differing ancient sources to be the wife, sister, or daughter of Faunus (the Roman counterpart of Pan). Varro regarded her as the female counterpart of Faunus, and said that the fauni all had prophetic powers. She is also called Fatua or Fenta Fauna.
Title: Bona Dea
Content:  Cicero makes no reference to any myth pertaining to Bona Dea. Later Roman scholars connected her to the goddess Fauna, a central figure in Latium's aristocratic foundation myth, which was thus re-embroidered as a Roman moral fable. Several variants are known; Fauna is daughter, wife or sister of Faunus (also named Faunus Fatuus, meaning Faunus "the foolish", or seer). Faunus was son of Picus, and was the first king of the Latins, empowered with the gift of prophecy. In Roman religion he was a pastoral god and protector of flocks, with a shrine and oracle on the Aventine, sometimes identified with Inuus and later, with Greek Pan. As 
Title: Temple of Faunus
Content:  The Temple of Faunus (Latin: aedes Fauni) was an ancient Roman temple on the southern end of the Tiber Island in Rome, dedicated to Faunus, the god of flocks. It was the only temple with that dedication in Rome itself. It was a hexastyle prostyle built in 196 BC by Gnaeus Domitius Ahenobarbus and Gaius Scribonius Libo and financed by a fine they had imposed on the shepherd of a flock which (probably) had accidentally grazed for free on a public field. It was dedicated in 194 BC on the Ides of February, anticipating by two days the major Roman festival of Faunus, the Lupercalia. If still in use by the 4th-and 5th century, it would have been closed during the persecution of pagans in the late Roman Empire.
Title: Kings of Alba Longa
Content:  of Mars, rather than Saturn. According to Justin, Faunus was Latinus' maternal grandfather, and was the son of Jupiter, rather than Picus; in this account Saturn was the first king of the Latins. According to Dionysius of Halicarnassus, Latinus was the son of Hercules, and merely pretended to be the son of Faunus; Aeneas arrived in the thirty-fifth year of his reign over the Aborigines. Evander and Janus are also sometimes described as ancient kings of the Aborigines; but Livy describes Evander as a king of the Arcadians, as does Virgil, who makes him an ally of Aeneas in the war
