Through Mosaic, Saline water and Rome

Depictions of Neptune in Roman mosaics, especially those in North Africa, were influenced by Hellenistic conventions. He was likely associated with freshwater springs before the sea; his festival, Neptunalia, took place on July 23, during the peak of summer when water was scarcest. Like Poseidon, he was also worshipped by the Romans as a god of horses, Neptunus equestris, who was also a patron of horse-racing.

Worship

The theology of Neptune is limited by his close identification with the Greek god Poseidon, one of many members of the Greek pantheon whose theology was later tied to a Roman deity. The lectisternium of 399 BC indicated that the Greek figures of Poseidon, Artemis, and Heracles had been introduced and worshipped in Rome as Neptune, Diana, and Hercules. It has been speculated that Neptune has been conflated with a Proto-Indo-European freshwater deity; since the Indo-Europeans lived inland and had little direct knowledge of the sea, the Romans may have reused the theology of a previous freshwater god in their worship of Neptune. Servius explicitly names Neptune as the god of rivers, springs, and waters; he may parallel the Irish god Nechtan, master of rivers and wells. This is in contrast to Poseidon, who was primarily a god of the sea.

Neptune has been associated with a number of other Roman deities. By the first century BC, he had supplanted Portunus as the god of naval victories; Sextus Pompeius called himself the "son of Neptune". For a time, Neptune was paired in his dominion of the sea with Salacia, the goddess of saltwater. Neptune was considered the legendary progenitor god of the Falisci (who called themselves Neptunia proles), joining Mars, Janus, Saturn, and Jupiter as the deific father of a Latin tribe.

Neptunalia

Neptunalia, the Roman festival of Neptune, was held at the height of summer (typically on July 23). The date of the festival and the construction of tree-branch shelters suggest that Neptune was a god of water sources in times of drought and heat. The most ancient Roman calendar set the feriae of Neptunus on July 23, between the Lucaria festival of the grove and the Furrinalia festival of July 25. All three festivals were connected to water during the period of summer heat (canicula) and drought, when freshwater sources were lowest.

It has been speculated that the three festivals fall in a logical order. The Lucaria was devoted to clearing overgrown bushes and uprooting and burning excess vegetation. Neptunalia followed, devoted to conservation and the draining of superficial waters. These culminated in the Furrinalia, sacred to Furrina (the goddess of springs and wells).

Neptunalia was spent under branch huts in a woods between the Tiber and the Via Salaria, with participants drinking spring water and wine to escape the heat. It was a time of merrymaking, when men and women could mix without the usual Roman societal constraints. There is an added context of agricultural fertility in the festival, since Neptune received the sacrifice of a bull.

Temples

Neptune had only one temple in Rome, the Temple of Neptune. It stood near the Circus Flaminius, the Roman racetrack in the southern part of the Campus Martius, and dates back to at least 206 BC. The temple was restored out by Gnaeus Domitius Ahenobarbus c. 40 BC, an event depicted on a coin struck by the consul. Within the temple was a sculpture of a marine group by Scopas Minor. The Basilica Neptuni was later built on the Campus Martius, and was dedicated by Agrippa in honor of the naval victory of Actium. This basilica supplanted the older temple, which had replaced an ancient altar.

Sacrifices

Neptune is one of only four Roman gods to whom it was considered appropriate to sacrifice a bull. The other three were Apollo, Mars, and Jupiter, although Vulcan (known in Greek mythology as Hephaestus) has also been depicted with the offering of a red bull and a red-bull calf. If an incorrect offering was presented, either inadvertently or due to necessity, additional propitiation was required to avoid divine retribution. This type of offering implied a stricter connection between the deity and the world.

Paredrae

Paredrae are entities who accompany a god, representing the fundamental aspects (or powers) of that god. With Hellenic influence, these paredrae came to be considered separate deities and consorts of their associated god. Earlier folk belief might have also identified paredrae as consorts of their god.

Salacia and Venilia have been discussed by ancient and modern scholars. Varro connects Salacia to salum (sea), and Venilia to ventus (wind). Festus attributed to Salacia the motion of the sea. Venilia brought waves to the shore, and Salacia caused their retreat out to sea. They were examined by the Christian philosopher St. Augustine, who devoted a chapter of De Civitate Dei to ridiculing inconsistencies in the theological definition of the entities; since Salacia personified the deep sea, Augustine wondered how she could also be the retreating waves (since waves are a surface phenomenon). He wrote elsewhere that Venilia would be the "hope that comes", an aspect (or power) of Jupiter understood as anima mundi.

Servius, in his commentary on the Aeneid, wrote about Salacia and Venilia in V 724: "(Venus) dicitur et Salacia, quae proprie meretricum dea appellata est a veteribus"; "(Venus) is also called Salacia, who was particularly named goddess of prostitutes by the ancient". Elsewhere, he wrote that Salacia and Venilia are the same entity.

Among modern scholars, Dumézil and his followers Bloch and Schilling centre their interpretation of Neptune on the direct, concrete, limited value and functions of water. Salacia would represent the forceful, violent aspect of gushing and overflowing water and Venilia the tranquil, gentle aspect of still (or slowly-flowing) water. According to Dumézil, Neptune's two paredrae (Salacia and Venilia) represent the overpowering and tranquil aspects of water, natural and domesticated: Salacia the gushing, overbearing waters, and Venilia the still (or quietly-flowing) waters.

Preller, Fowler, Petersmann and Takács attribute to the theology of Neptune broader significance as a god of universal worldly fertility, particularly relevant to agriculture and human reproduction. They interpret Salacia as personifying lust, and Venilia as related to venia: ingratiating attraction, connected with love and the desire for reproduction. Ludwig Preller cited a significant aspect of Venilia; she was recorded in the indigitamenta as a deity of longing or desire. According to Preller, this would explain a theonym similar to that of Venus. Other data seem to agree; Salacia would parallel Thetis as the mother of Achilles, and Venilia would be the mother of Turnus and Iuturna by Daunus (king of the Rutulians). According to another source, Venilia would be the partner of Janus, with whom she mothered the nymph Canens (loved by Picus). These mythical data underline the reproductive function envisaged in the figures of Neptune's paredrae, particularly that of Venilia, in childbirth and motherhood. A legendary king Venulus was remembered at Tibur and Lavinium.
