<p>Temple precinct of Diana Aventina in the *Lauretum on the *Aventine, the main sanctuary of the goddess in Rome (<i>Diana Aventina</i>: Prop. 4.8.29, Mart. 6.64.13; or <i>Aventinensis</i>: e.g., Festus 164) and a place of strong plebeian self-representation. Allegedly founded by the slave-born Servius Tullius, the sanctuary was once the assembly-place of the Latin cities under Rome’s leadership and also a notable asylum (Livy 1.45.2-3; Dion. Hal., <i>Ant. Rom.</i> 4.26.2-5); its festival on the Ides of August continued to be the holiday of slaves (Festus 460). Further, the sanctuary served as an important archive for legislation; a bronze pillar, still standing in the Augustan period (Dion. Hal., <i>Ant. Rom.</i> 4.26), included the Icilian law of the mid-5th c. B.C. <i>de Aventino publicando</i> which provided allotments of Aventine land to the <i>plebs</i> (Livy 3.31.1; Dion. Hal., <i>Ant.Rom.</i> 10.32.1-5).</p>
<p>No remains of this temple have been identified, yet the building and its precinct are represented on fragment 22 of the Severan Marble Plan, next to the Temple of *Minerva (Carettoni <i>et al.</i>, <i>Pianta</i> 79-80, pl. 23, frags. 22 a,b now lost; Rodríguez Almeida, <i>Forma</i> pl. 15; Richardson 108: “almost certainly”; Vendittelli, <i>LTUR</i> 12; cf. <i>Templum Dianae et Minervae</i> in the Regionary Catalogues, <i>Regio XIII</i>). Under the Augustan program of ‘adorning the city’, the temple was rebuilt or restored by L. Cornificius (Suet., <i>Aug</i>. 29.4: <i>a L. Cornificio aedes Dianae</i>). Since the name DIANA CORNIF. is attested independently (<i>CIL</i> VI 4305=<i>ILS</i> 1732), the label CORNIFICIA[... on the Marble Plan clearly refers to <i>Diana Cornificia</i> or <i>Cornificiana</i> and thus establishes the identification. The footprint of the octostyle podium temple shown on the 3rd-c. A.D. fragment is presumably still that of Cornificius’ building; it is surrounded by a precinct with a double-colonnaded portico (or, perhaps, a double line of trees: Richardson 108) along its flank (its likely twin, as well as a portico along the rear side, are tentatively depicted on our map).</p>
<p>The position of fragment 22, never securely fixed, comes under debate as a result of recent excavations. The traditional position falls within rather narrow spatial limits, about halfway between S. Sabina and S. Prisca, and depends upon the adjacent <i>balneum Surae</i> fragment (frag. 21). The long street on fragment 21 had been plausibly identified with the ancient street found under the modern Via di S. Prisca (for the arrangement: Scagnetti; Vendittelli 1987, 34 fig. 2; ead. 1988, 109 fig. 10), and thus both fragments 21 and 22 are fairly securely positioned. However, Vendittelli’s revision of the Aventine topography places fragment 22 about 300 m further SE, under S. Alessio (1990, 163 fig. 1, 164 fig. 2), based upon a tentative identification of some excavated walls with those on the <i>balneum Surae</i> fragment (1990, 166 fig. 4). More importantly, Vendittelli’s thesis requires the Marble Plan’s joint lines be altered by no less than 25°, which is not acceptable; in addition, the placement of fragment 22 under S. Alessio ignores the existence of an ancient street under the modern Via di S. Sabina (s.v. *Vicus Armilustri). Vendittelli’s latest assessment (<i>LTUR</i> 12-13) places fragment 22 at about the same site (with the Temple of Diana falling at the junction of Via di S. Alberto Magno with Via di S. Sabina); yet previously she had rejected this location (1987, 34 fig. 2), and once again the ancient street under Via di S. Sabina is ignored. All this confirms, at least indirectly, a certain legitimacy of the previous assumptions; our map follows — albeit with caution — the position of fragment 22 as advanced on Vendittelli’s earlier plans (1987 and 1988) and as rendered by Scagnetti.</p>
