Lares belonged within the "bounded physical domain" under their protection, and seem to have been as innumerable as the places they protected. Some appear to have had overlapping functions and changes of name. Some have no particular or descriptive name: for example, those invoked along with
Mars in the
Carmen Arvale are simply (an archaic form of ), whose divine functions must be inferred from the wording and context of the Carmen itself. Likewise, those invoked along with other deities by the consul
Publius Decius Mus as an act of before his death in battle are simply . The titles and domains given below cannot, therefore, be taken as exhaustive or definitive.
The were the Lares of the city of Rome, later of the Roman state or community; literally, the "Lares who stand before", as guardians or watchmen.
Ovid, a 1st-century CE
Roman poet, in his
Fasti, claims that the epithet was applied to the Lares as they "stand for us, and preside over the city walls, and they are present and bring us aid." According to
Festus, a 2nd-century Roman grammarian, the term "" was a term used by the "ancients" ("") as a synonym for "" ("overseer, high priest"). It is also possible that the religious concept of the may connect to the
Umbrian goddess , whose name is mentioned in the
Iguvine tablets. Etymologically, the linguist
Benjamin W. Fortson IV suggests
Umbrian and Latin may reflect an earlier pre-form of the shape ("protectress"). Ovid may imply that the were of
Sabine origin, although the exact meaning of the passage is obscure due to the corruption of the manuscript tradition. The current
Loeb Classical Library edition of the
Fasti, which was translated by
James G. Frazer in 1931, renders the sentence in question as "," which it renders as "Curius indeed had vowed them." However, the classicist
Harriet I. Flower suggests that the text may reference the Sabine town of
Cures. The 1st-century BCE Roman author
Varro claims that the —along with numerous other deities—were "dedicated" at Rome ("") by
Titus Tatius, a legendary king of the Sabines. Moreover, the Greek author
Strabo claims that Titus Tatius and
Numa Pompilius both originated from the city of Cures. Ovid also describes a story in which the
naiad Lara, after being raped by
Mercury, becomes
mother to the Lares. The classicist
T. P. Wiseman connects this legend to a scene on a Praenestine mirror that depicts two infants suckling the breasts of a
she-wolf. Wiseman interprets this scene as a representation of the story of the
foundation of Rome, though he does not consider the twins to equate to
Romulus and Remus, as—according to Wiseman—the assumption that the mirror portrays the standard version of the myth creates issues with the identification of the other figures in the artwork. Instead, Wiseman suggests that the mirror portrays
Hermes and
Tacita—who was identified by Ovid with Lara—and that the children are the . Wiseman's interpretation is not universally accepted, with the classicist
Ana Mayorgas Rodriguez stating that "although the surrounding figures cannot be recognised certainly, it is still most probable that the children are Romulus and Remus." According to the classicist
Tim Cornell, a possible connection between the and the founding of Rome may itself relate to a potential characterization of the as "deified ancestors." Wisseman further argues that the possible presence of the on this mirror could indicate that the standard story of Romulus and Remus did not exist by 340 BCE—around the date of the creation of the mirror. However, the classicist
Fay Glinister criticizes this argument, stating that it relies upon ignorance of "early iconographic evidence." The were housed in the state
Regia, near the temple of Vesta, with whose worship and sacred hearth they were associated; they seem to have protected Rome from malicious or destructive fire. They may have also functioned as the neighbourhood Lares of Octavian (the later emperor Augustus), who owned a house between the Temple of Vesta and the Regia. Augustus later gave this house and care of its Lares to the Vestals: this donation reinforced the religious bonds between the Lares of his household, his neighbourhood, and the State. His reforms extended this identification to every neighbourhood Lares shrine. However, and the (renamed ) should probably not be considered identical. Their local festivals were held at the same shrines, but at different times. According to Ovid, this altar had decayed due to the wears of time, which may—according to classicist
Howard Scullard—indicate waning interest in the . Ovid also mentions a carved-out statue of a dog placed by this same altar. Another theory, advanced by the classicist
Christopher A. Faraone, relates the canine symbolism to
Assyrian guardian statues.

Lares Augusti: the Lares of

The sow's body was said to be kept at Lavinium, preserved in salt brine as a sacred object.
