<p>A grotto at the base of the SW *Palatine, near the *Circus Maximus, believed to be the site where Faustulus discovered Romulus and Remus with the she-wolf (Dion. Hal., <i>Ant. Rom.</i> 1.79.8, Livy 1.5.1-2, Ovid, <i>Fast</i>. 2.381-424). The site featured a spring, and was once surrounded by a grove; the original <i>ficus Ruminalis</i> grew here, but by the Augustan period, only <i>vestigia</i> of the fig-tree remained near the Lupercal (Ov., <i>Fast.</i> 2.411; cf. *Forum; Richardson; Coarelli; Pliny, <i>NH</i> 15.77-78; Tac., <i>Ann</i>. 13.58).</p> <p>Following literary sources, the Lupercal can be located on the lower SW Palatine. Dionysius of Halicarnassus places it at the foot of the <i>Germalus</i> (s.v. Palatine) between the *Velabrum and *Circus Maximus (<i>Ant. Rom.</i> 1.79.8), and also associates the grotto with the Temple of *Victory, which stood atop the SW Palatine (<i>Ant. Rom.</i> 1.32.5). Further, the Lupercal is described as <i>in Circo</i>, ‘at the Circus [Maximus]’ (Servius, <i>ad Aen.</i> 8.90), and used as a landmark for a Palatine theater proposed but never realized by C. Cassius Longinus (<i>c</i>. 154 B.C., <i>a Lupercali in Palatio</i>: Vell. Pat. 1.15.3; Richardson 239).</p> <p>Augustus takes credit for building the Lupercal (<i>RG</i> 19: <i>feci</i>); although what this meant architecturally is unclear, an imperial intervention would have entailed significant alterations (Coarelli, <i>LTUR</i>; Wiseman 15). Concurrently, the festival of the <i>Lupercalia</i> was reorganized by Augustus (Suet., <i>Aug.</i> 31.4; on the <i>Lupercalia</i>, Wiseman; cf. *Magna Mater, Aedes). Within the Lupercal were several statues, including a bronze depiction of the she-wolf suckling the twins (Dion. Hal., <i>Ant. Rom.</i> 1.79.8; Livy 10.23) and an equestrian statue of Drusus (<i>CIL</i> VI 912=31200). The presence of an equestrian monument suggests the change in atmosphere the Augustan rebuilding may have brought to a once idyllic, watery grove.</p> <p>Returning to an early theory advanced by Lanciani, Coarelli suggests that a grotto near the Church of S. Anastasia may be the Augustan Lupercal (<i>LTUR</i>; contra, Richardson). First excavated in 1534, this cave was decorated as a <i>nympheum</i> with its walls “encrusted in marine shells” (Lanciani); Coarelli argues, as does Shipley, that this decoration would be appropriate for the Lupercal. Complicating matters is a series of Augustan tufa walls which stand just E of the apse of S. Anastasia (Whitehead pl. 11, A and B; Lanciani, <i>FUR</i> pl. 29); despite their partial preservation, the walls seem to have belonged to a warehouse similar to the *Horrea Agrippae (Whitehead). This suggests further study is needed before Coarelli’s proposal can be accepted, and thus the Lupercal has been represented by an index number on our map.</p>
