A lifeguard at work on a beach in Central Italy did double duty this weekend when he took on the role of amateur archaeologist after a beachgoer came across a 2nd-century amphora during a leisurely walk, according the Italian news outlet Il Messaggero.

The conditions along the beach in Latina, the capital of Italy’s Lazio region, were perfect for a stroll: the day was hot, in the low 80s, and the sea was exceptionally clear. Incidentally, those are the same conditions that make finding an artifact from antiquity as easy as skipping stones.
