<p>The Temple of Iuno Moneta on the *Arx was vowed by L. Camillus and dedicated in 345/43 B.C. (Livy 7.28.4-6: <i>aedem Iunoni Monetae ... in Arce</i>). Ovid states that it was located ‘on the summit of the Arx’ (<i>Fast.</i> 6.183: <i>Arce ... in summa Iunoni templa Monetae</i>). This puts the temple under the Church of S. Maria in Aracoeli. A recent contention that this church stands on an artificial platform of demolished structures and imported earth that have raised its foundations considerably above the natural level of the hill (Giannelli 1978, 69-70), so that the highest point of the Arx in antiquity was actually the area of the Aracoeli garden to the SE (Giannelli 1980-81, Coarelli), has been disproved by a re-evaluation of the geology (Ammerman and Terrenato). So whereas Giannelli (1978, 63-66) identified the Temple of Iuno Moneta with the tufa remains in the Aracoeli garden, as accepted by Claridge and Ziolkowski, we return to the traditional view which places the temple under the church of S. Maria in Aracoeli (Richardson, von Sydow, Platner–Ashby), the highest point of the Arx. Indeed, part of a temple survives under this church (Giannelli <i>LTUR</i>). The Republican mint of Rome also stood on the summit of the Arx next to the Temple of Iuno Moneta (for the mint, s.v. *Tabularium).</p> <p><i>Addendum</i></p> <p>Recent investigations show that the Temple of Iuno Moneta was not located under the church of S. Maria in Aracoeli: P.L. Tucci, “L'Arx Capitolina: tra mito e realta,” in L. Haselberger and J. Humphrey (edd.), <i>Imaging ancient Rome</i> (JRA Suppl. 61, 2006) 63-73, esp. 64-67. This would appear to strengthen the case for identifying the temple with the foundation walls in the Aracoeli garden, but the fact remains that the Temple of Iuno Moneta was understood by Ovid to have stood 'on the summit of the Arx' (<i>Fast</i>. 6.183). It now seems that the highest point of the Arx was NE of S. Maria in Aracoeli: P.L. Tucci, “‘Where high Moneta leads her steps sublime’. The ‘Tabularium’ and the Temple of Juno Moneta,” <i>JRA</i> 18 (2005) 6-33. This is where Tucci places the Auguraculum and the Temple of Concordia <i>in arce</i> (15, 19 n.49). In my view it is here, NE of the Aracoeli church at the highest point of the Arx, that the Temple of Iuno Moneta is now best located. Further discussion will certainly be necessary, not least because Tucci accepts Giannelli's identification of the Iuno Moneta temple with the foundations in the Aracoeli garden, but argues that this site was abandoned in the Sullan period and the temple rebuilt in a new position on top of the ‘Tabularium’ (19-25).</p>
