This drawing of a tomb, added to the codex in the seventeenth century, is identified in the caption as being located just beyond the church of Sant’Agnese. It was tentatively identified by Ashby (1904) on the basis of an earlier drawing of the same structure by Francesco da Sangallo in the Codex Barberini, which is labelled as standing just beyond the Ponte Nomentano over the River Aniene. Ashby later connected this identification with the then-surviving concrete core of a tomb in this vicinity (Ashby 1906, p. 46). The Coner plan (as Ashby realised) is a copy of the Barberini drawing, although with minor differences. Thus, whereas the Coner plan shows the tomb as having stepped embrasures that are all axially aligned, the Barberini drawing represents two of them (those to left and right) as skewed so that the openings in the exterior faces are off-centre with respect to the external half-columns that frame them; and whereas the Coner plan shows the external half-columns and corner pilasters as having undecorated shafts, the Barberini drawing depicts them as fluted. Both drawings, however, show the pilasters as being wider than the half-columns, and the central bays of the three on each side as being narrower than the others, and this is confirmed by a schematic plan included on a drawing by Giovanni Francesco da Sangallo. Another Coner drawing, one produced by Bernardo della Volpaia, records in detail the Doric capital of a half-column, which is indeed fluted, together with the entablature above it.
