<p>The shrine of the archaic divinity Murcia (<i>sacellum</i>: Varro, <i>Ling</i>. 5.154) stood within the track of the *Circus Maximus near the first turning post (the SE <i>meta</i>) on the *Aventine side (Tert., <i>De spect.</i> 5, 8; <i>sub monte Aventino</i>: Festus 135; see fig. 9). Varro relates that the small shrine was once surrounded by a grove, but this had been reduced to a single myrtle tree, a <i>vestigium</i>, by the Augustan era (Varro, <i>loc. cit.</i>). In late antiquity the valley was called the <i>vallis Murcia</i> after the goddess, but perhaps only after her shrine had been substantially enlarged (Humphrey 96-97; Coarelli; s.v. *Vallis: Circus Maximus). Since nothing is known of the shrine’s Augustan architecture, and its location can only be approximated, it is represented by an index number on our map.</p>
