<p>A mid-Republican temple of Ops, the goddess of wealth, stood <i>in Capitolio</i> and was struck by lightning in 186 B.C. (Livy 39.22.4: <i>aedes Opis in Capitolio</i>). It was probably dedicated by L. Caecilius Metellus in 250 B.C. (Aronen, with Pliny, <i>NH</i> 11.174: <i>in dedicanda aede Opi opifere</i>; cf. Ziolkowski); it existed in the Augustan period, for it was here that women and children assembled for the celebration of the <i>ludi Saeculares</i> of 17 B.C. (<i>CIL</i> VI 32323). The Temple of Ops is believed to have stood next to the Temple of *Fides: military diplomas of the 1st c. A.D. were attached to both temples; a storm in 44 B.C. damaged both temples (Obsequens 68), and the concepts of <i>fides</i> and <i>ops</i> (faith and wealth) were closely related (Aronen). Aronen identifies the Temples of Fides and Ops with the twin temples shown on a fragment of the Severan Marble Plan (Rodríguez Almeida, <i>Forma</i> pl. 23, frag. 31 a,b,c; s.v. *Capitolium: Marble Plan Temples); but this is unlikely, for the Temple of Fides almost certainly stood in the SW corner of the *Area Capitolina, best identified with a temple shown on an adjoining fragment of the Severan Marble Plan (Carretoni <i>et al.</i>, <i>Pianta</i> frag. 499; s.v. *Fides). The Temple of Ops stood close by, perhaps set back from the <i>temenos</i> wall of the Area Capitolina, given that an altar of Isis Deserta stood ‘behind the Temple of Ops’ (Schol. Veron., in Verg. <i>Aen</i>. 2.714; noted by Rodríguez Almeida). Its approximate position is marked on the map following Coarelli and von Sydow.</p>
