<p>Burial monument in the W *Campus Martius, built for A. Hirtius, consul in 43 B.C. and killed during the battle of Mutina the same year. A public burial in the Campus Martius was granted to him and his co-consul of 43 B.C., C. Vibius Pansa Caetronianus (s.v. *Sepulcrum: C. Vibius Pansa; Livy, <i>Per.</i> 119; Vell. Pat. 2.62.4). Remains of the tomb precinct have been identified with brick walls (H. 2.65 m) covered by a course of slanted travertine blocks standing beneath Palazzo della Cancelleria (Magi, Colini, Nogara) at the *Euripus. The actual burial chamber inside the precinct has disappeared, perhaps reused as building material (intensive activity of <i>marmorari</i> has been revealed by numerous late-antique inscriptions and the presence in the tomb of fragmentary sculptures from later periods). The identification of the structure as the <i>sepulcrum</i> of Hirtius is supported by the presence of three <i>cippi</i> carrying the inscription A. HIRTIVS A. F. which were inserted at the corners of the brick precinct wall (<i>ILLRP</i> 419). From a passage of Cicero (<i>Brut.</i> 1.15-18) it can be assumed that Hirtius and Pansa found their resting place in the Horti of Mark Antony (s.v. *Horti: Agrippa) (Coarelli 1997, 290).</p>
