Gaius Plinius Secundus, HN  36.24.114  (ca. A.D. 65): Signa aerea inter columnas, ut indicavimus, fuerunt iii numero; cavea ipsa cepit hominum LXXX, cum Pompeiani theatri totiens multipicata urbe tantoque maiore populo sufficiat large XXXX sedere. The bronze statues in the spaces between the columns [in the "temporary" theater of Scaurus] numbered 3,000 as I mentioned earlier. As for the auditorium, it accomodated 80,000; and yet that of Pompeius' theater amply meets all requirements with seats for 40,000 even though the city is so many times larger and the population so much more numerous than it was at that time.
