<p>Marble tomb belonging to an Octavia, daughter of a Marcus Octavius (perhaps M. Octavius Cn. f., <i>RE</i> XVII Octavius 94), and probably wife to an Appius, dating to the mid-1st c. B.C. (<i>CIL</i> VI 23330; Lega, Castagnoli). The tomb was discovered in 1616 near the intersection of Via di Porta Pinciana and Via Sistina (<i>CAR</i> II, H no. 16); after it was drawn and recorded by Grimaldi, the tomb was dismantled for <i>spolia</i> (Castagnoli pl. 10 where <i>Cod. Vat. Lat.</i> 6438, 400 is reproduced). Grimaldi sketched a flat-roofed, rectangular façade preceded by a shallow, distyle, Ionic porch whose architrave bore the epitaph. The tomb probably had a rectangular plan with the inscription and entrance on opposite sides; Grimaldi did not include dimensions, so the tomb’s depth has been estimated (<i>c</i>. 5 m) based on comparison with similar tombs (cf. *Sepulcrum: C. Publicius Bibulus, *Sepulcrum: Sempronii).</p>
