<p>Sanctuary on the SW *Palatine where poets honored Bacchus with an annual festival (Ov., <i>Trist</i>. 5.3; cf. Hor., <i>Carm</i>. 3.25), probably located near the *Domus of Augustus and the Palatine Temple of *Apollo (Rodríguez Almeida). Propertius mentions an altar (3.17.1) and a sacrifice ‘in front of the doors to the sanctuary’ (3.17.38: <i>ante fauces templi</i>); he also suggests a site near the Temple of *Magna Mater (3.17.35: <i>iuxta dea magna Cybele</i>). The sanctuary existed through, at least, the 2nd c. A.D., as Pausanius mentions a mammoth boar’s tusk kept ‘in the sanctuary of Bacchus’, ἐν ἱερῷ Διονύσου (8.46.5). Given the terms employed by the ancient authors (<i>templum</i>, <i>ara</i>, ἱερόν), the shrine of Bacchus was probably an altar enclosure (Rodríguez Almeida). It is marked by an index number on the SW Palatine, though its exact position in that region cannot be determined.</p>
