<p>Inscriptions belonging to the marble compital <i>aedicula</i> (shrine) of the <i>vicus Cornicularius</i> were found in the course of foundation work for the Nuova Esattoria at the foot of the *Oppian’s S slope (Moretti, Cozza; found near Republican-Augustan housing remains: s.v. *Domus: Oppius Mons [2]). The oldest inscription dates from A.D. 22 and lists the <i>magistri</i> of the <i>vicus</i> ‘in the 27th year’, which means that this <i>vicus</i> was established in 6/5 B.C. (Moretti 232-34 no. 3: VICI COR]NICVLARI; Cozza 148 no.1; Lega); a second inscription, which dates between A.D. 53 and 55, records the location of the <i>vicus</i> in <i>Regio III</i> (Moretti 231-32 no. 1: VICI CORNICLAR[I]; Cozza 148-49 no. 2; on a connection of the <i>vicus</i> with workers in horn (<i>corniculum</i>), rather than with military adjutants (<i>cornicularii</i>): Moretti 234; Lega; left open by Richardson). While the precise findspot within the lot of the Esattoria has not been documented, the inscriptions were “evidently found <i>in situ</i>” (Moretti 234; accepted by Richardson and, implicitly, by Lega), thus the area of the <i>vicus</i>-neighborhood can be approximated with some certainty. Our map labels the quarter of the Vicus Cornicularius, with an index number indicating the findspot of the inscriptions.</p>
