<p>The Temple of Augustan Concord at the foot of the *Capitolium overlooking the *Forum. According to Roman tradition, the Temple of Concord was originally vowed by Camillus during patrician-plebeian struggles in 367 B.C. (Plut., <i>Cam</i>. 42.3). Although the people voted to build the temple on behalf of Camillus (Plut., <i>Cam</i>. 42.4), it is unclear whether this temple was ever built, though recent excavations have uncovered 4th-c. B.C. remains on the site (Ferroni). A temple to Concordia was definitely built by L. Opimius in 121 B.C. following the death of C. Gracchus (App., <i>B Civ</i>. 1.26; Plut., <i>C. Gracch</i>. 17.6), but this temple burned, perhaps in 9 B.C. (cf. Dio Cass. 55.1.1). Tiberius vowed to restore the temple in 7 B.C. (ibid. 55.8.2) and the rebuilt temple, now to <i>Augustan</i> Concord, was dedicated in the names of Tiberius and his dead brother Drusus (Ov., <i>Fast</i>. 1.647-48; Degrassi, <i>Inscr. Ital</i>. 13.2: <i>Fast. Praen.</i> 115: CONCORDIA AV[G(VSTAE) ...]; <i>Fast. Verul. </i> 161: AEDES C[O]NCORDIAE IN FORO) in A.D. 10 (Dio Cass. 56.25.1) or 12 (Suet., <i>Tib</i>. 20).</p> <p>The visible remains of the temple are from the Augustan phase. The <i>cella</i>, which abuts the *Tabularium, has a transverse axis, an unusual design that maximizes the available space. The new temple probably covered the Volcanal, an altar to Vulcan said to have been erected by Titus Tatius (Richardson; cf. *Saturnus, Ara). The NE façade of the <i>pronaos</i> and the NE half of the <i>cella</i>, now underneath the adjacent staircase ascending the Capitolium, are restored on the principle of symmetry (cf. Gasparri; <i>LTUR</i> I, fig. 188).</p>
