HORREA PETRONIANA
known from two sepulchral inscriptions, one
(
CIL vi. 3971) of a slave of Nero, the other erected by one M. Aurelius
Xenonianus Aquila, a Bithynian, who had a 'statio' in these horrea;
as he calls himself
πρῶτος λιθενπόρων, they must have been among the
marble warehouses (
RAP iii. 191-196; see
EMPORIUM, MARMORATA).
