NEMAIN (Nemainn, Nemon,Neman, Némain, Neamhain, Nemhain,Nemain )was a shadowy early Irish war-goddess, and wife or consort of Néit son of Induí son of Tuireann Delbáeth, along with Fea Badb, whose identity she may share. Old Irish texts cite three goddesses of war, Badb, Macha, and Mórrígan, known collectively as Mórrígna. Sometimes Nemain is substituted in the trio for either Badb or Mórrígan.
The Battersea Shield is one of the most significant pieces of ancient Celtic military equipment found in Britain. It is a sheet bronze covering of a (now vanished) wooden shield decorated in La Tène style. The shield is on display in the British Museum. It is believed that the shield was cast into the Thames as a votive offering and was never used in battle. The Battersea Shield probably dates from the 1st century BC or early 1st century AD, but dates as early as 350 BC have been suggested.
