<p>This Temple to Iuno Lucina on the *Esquiline (IVN[O]NI LVCINAE EXQVILIIS ... AEDIS: <i>Fast. Praen.</i>, in Degrassi, <i>Inscr. Ital.</i> 13.2, 121) was founded by Roman matrons in 375 B.C. and only later became an <i>aedes publica</i> (Ziolkowski). It was restored in 190 and 41 B.C. It was situated in a small grove, or <i>lucus</i> (Varro, <i>Ling.</i> 5.49; Pliny, <i>NH</i> 16.235) on the *Cispian as listed in the <i>sacraria Argeorum</i> (Varro, <i>Ling.</i> 5.49-50). The general consensus thus places this temple just N of the *Clivus Suburanus on the S slopes of the Cispian (Ziolkowski, Giannelli, Richardson). But this location is not consistent with an inscription relating to the restoration of the perimeter wall by Q. Pedius in 41 B.C. (<i>CIL</i> VI 358), found under the Monastery of S. Francisco de Paula, apparently <i>in situ</i>. The monastery (for its location, see Panella; Lanciani, <i>FUR</i> pl. 23) lies S of Via di S. Lucia in Selci (the Clivus Suburanus), and so on the *Oppian, not the Cispian. Unfortunately, this ambiguity cannot be resolved. The location adopted here gives preference to Varro over the editors of <i>CIL</i>: N of the Clivus Suburanus, but as close as possible to the findspot of the inscription. For a highly conjectural placement of a grove of Iuno Lucina under the Church of S. Maria Maggiore, see De Spirito.</p>
