<p>Gate in the Servian Wall (*Muri: Aventinus) on the *Aventine without identified remains but known from textual sources, especially Varro’s catalogue of gates (<i>Ling</i>. 5.163: <i>Rauduscula</i> [sc. <i>porta</i>]; further, Val. Max. 5.6.3: <i>dictaque Rauduscula</i>; Paulus, in Festus 339: <i>Rodusculana porta</i>); in various ways, these sources derive the gate’s name from <i>raudus</i>, ‘copper or bronze’ (with Paulus, in Festus 339, alternatively from <i>rudis</i>, ‘unpolished’). Since the Capitoline base (<i>CIL</i> VI 975=<i>ILS</i> 6073, A.D. 136) situates the neighborhood of the <i>vicus portae R(a)udusculanae</i> in <i>Regio XII</i> and, in addition, Varro’s catalogue lists the gate between the *Porta Naevia and the *Porta Lavernalis (both likewise unidentified), there is general agreement (e.g., Lanciani, <i>FUR</i> pl. 41; Richardson; Coarelli) that the Porta Rauduscula marked the intersection of the Servian Wall with a Republican street likely to have followed the central depression of the Aventine (s.v. *Aventinus: Street). While the existence of a gate is plausible, its identification remains entirely hypothetical. Thus, our map accepts the site of a gate but refrains from naming it.</p>
