Found at the Villa Muti in the environs of Frascati, Italy. Purchased from Dr Jacob Hirsch in 1954.
The names of the two men (left to right) are P. Licinius Philonic(us)
and P. Licinius Demetrius. The two are presumably freedmen. The left border shows the fasces; on the right is a bow and drill, a knife (or socketed chisel?), and an adze-hammer, along with a tanged chisel (without handle). The “pediment” on top shows a hammer, tongs, and an anvil, perhaps the set-up for a minting coins.
CIL XIV 2721, 2722:
P(ublius) Licinius P(ubli) l(ibertus) / Philonicu[s] // P(ublius) Licinius P(ubli) l(ibertus) / Demetrius patrono / fecit […].
Publius Licinius Philonicus, the freedman of Publius; Publius Licinius Demetrius, the freedman of Publius, made [this tombstone] to [his] patron.
Museum description: On the left are the rods and axes used in the ceremony of freeing a slave. In the pediment are the tools of a smith or moneyer, and, on the right, the tools of a carpenter.
