Lewis chessmen
The Lewis chessmen (Scottish Gaelic: Fir-thàilisg Leòdhais [fiɾʲˈhaːlɪʃkʲ loː.ɪʃ]) or Uig chessmen, named after the island or the bay where they were found, are a group of distinctive 12th-century chess pieces, along with other game pieces, most of which are carved from walrus ivory. Discovered in 1831 on the Isle of Lewis in the Outer Hebrides of Scotland, they may constitute some of the few surviving medieval chess sets, although it is not clear if a single complete period-accurate set can be assembled from the pieces.
