The so-called “Dii Consentes” is a marble disc part of an altar from the I cent. CE, that depicts the twelve gods of the Roman pantheon surrounded by a frieze with zodiacal symbols. Its name translates to “Harmonious Gods” or “Concordant Gods”. Livy, in his ‘Ad Urbe Condita‘ (XXII.10.9), matches the gods in pairs: Jupiter-Juno, Neptune-Minerva, Mars-Venus, Apolo-Diana, Vulcano-Vest and Mercury-Ceres. The piece was discovered in a city called Gabii (Lazio), today, lies on display in the Louvre Museum. Its maximum diameter is 83.5cm (c. 33in) and the middle concavity measures 26.5 cm (c. 10in). Each deity is accompanied by its attribute: Jupiter with lightning, Neptune with Trident, Venus and Mars are linked by the Cupid etc.
