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.
[G. Dumézil ''Fêtes romaines d' été et d' automne. Suivi de Dix questions romaines'' Paris 1975 1. "Les eaux et les bois" p. 25-31.]
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

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.
[Varro apud Augustine '' De Civitate Dei'' VII 22.] 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''.

[William Warde Fowler ''The Religious Experience of the Roman People'' London, 1912, Appendix II.]
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

Perhaps influenced by Poseidon Ίππιος, Consus (whose festival included horse races) was reinterpreted as ''Neptunus equestris''; for his underground altar, he was identified with Poseidon Ένοσίχθων.

His arcane cult, which required the unearthing of the altar, indicate the deity's antiquity and

Neptune is a god of fertility, including human fertility. According to Stephen Weinstock, Jupiter is present in each of the first three regions with different aspects related to each region; Neptune should have been in the second region, and Pluto in the third. The reason for Neptune's displacement to region X is unclear. It is consistent with the collocation in the third quadrant of the deities related to the human world.

Ludwig Preller,
Karl Otfried Müller and

Fertility deity and divine ancestor
In lectures delivered during the 1990s, German scholar Hubert Petersmann proposed an etymology from the Indo-European root ''*nebh-'' ("damp, wet") with the suffix ''-tu'' (for an abstract verbal noun) and the adjectival suffix ''-no'' (domain of activity). The root ''*nebh-'' gives the Sanskrit ''nābhah'', Hittite ''nepis'', Latin ''nubs'', ''nebula'', German ''Nebel'', and the Slavic ''nebo''. The concept would be close to that expressed in the name of the Greek god ''Όυράνος'' (''

31. 3: "''uterque Neptunus''".
According to Petersmann, the ancient Indo-Europeans also venerated a god of wetness as the generator of life; this is indicated by the
Hittite theonyms ''nepišaš (D)IŠKURaš'' or ''nepišaš (D)Tarhunnaš'' ("lord of sky wet"), the sovereign of Earth and humanity. Although this function was transferred to Zeus/Jupiter (the sovereigns of weather), the old function survived in literature: the ''Aeneid'' V 13-14 reads, "''Heu, quianam tanti cinxerunt aethera nimbi?/ quidve, pater Neptune, paras?''" ("What, why have so many clouds enringed the sky? What are you preparing, father Neptune?") The indispensability of water and its connection to reproduction are universally known.
Müller and Deeke interpreted Neptune's theology as a divine ancestor of the Latin Faliscans: the father of
Messapus and Halesus, their heroic founders.
William Warde Fowler considered Salacia the personification of the virile potency which generated a Latin people, parallel with Mars, Saturn, Janus and Jupiter.
