 The earliest metal bells, one found in the Taosi site, and four in the Erlitou site, are dated to about 2000 BC.Though the bells for shepherding were expanded from the fertile crescent to Celtic, Carthaginian, Greek and Roman cultures, in Europe the earliest written evidence of bells used for livestock dates to the late 14th to early 15th century.Grimm's "Deutsches Wörterbuch" s.v.
