Dii Consentes

[2] The gods were listed by the poet Ennius in the late 3rd century BCE in a paraphrase of an unknown Greek poet:[3] Juno, Vesta, Minerva, Ceres, Diana, Venus Mars, Mercurius, Iovis, Neptunus, Vulcanus, Apollo Livy[4] arranges them in six male-female pairs: Jupiter-Juno, Neptune-Minerva, Mars-Venus, Apollo-Diana, Vulcan-Vesta and Mercury-Ceres.

[5]: 144–186 Herodotus mentions a group of twelve gods in Egypt, but this cannot be confirmed in any Egyptian sources.

[citation needed] The Greek cult of the Twelve Olympians can be traced to 6th century BCE Athens and has no apparent precedent in the Mycenaean period.

[5]: 144–186 The references to twelve Etruscan deities come from later Roman authors, writing long after the influence of the Greek pantheon had become dominant, and must be regarded with skepticism.

[5]: 232 Scholarly evaluation of this account depends on the hypothesis that the Etruscans originally immigrated to Italy from Anatolia.

Although the ritual purpose of this 1st century BCE altar from Gabii is unclear, the twelve deities depicted correspond to the Dii Consentes
