The Helmet of Agighiol is a Geto-Dacian silver helmet dating from the century BC, housed in the National Museum of Romanian History, Bucharest. It comes from the Agighiol area, in the Tulcea County, Romania.
The shorter variant was called sica (sickle) in the Dacian language (Valerius Maximus, III,2.12) with a blade length that varied but usually around 16 inches (41 cm) long with a handle 1/3 longer than the blade. The two-handed falx was more of a pole-arm. It consisted of a 3 feet (0.91 m) long wooden shaft with a long curved iron blade of nearly-equal length attached to the end.
