According to [[Tacitus]], '''Calgacus''' (sometimes '''Calgacos''' or '''Galgacus''') was a chieftain of the [[Caledonian Confederacy]] who fought the [[Ancient Rome|Roman]] army of [[Gnaeus Julius Agricola]] at the [[Battle of Mons Graupius]] in northern [[Scotland]] in AD 83 or 84. His name can be interpreted as [[Common Brittonic|Brittonic]] *{{lang|cel-x-combrit|calg-ac-os}}, 'possessing a blade', and is seemingly related to the [[Scottish Gaelic|Gaelic]] {{lang|gd|calgach}} (meaning 'prickly' or 'fierce'). Whether the word is a name or a title is unknown.<ref name=penelope>[http://penelope.uchicago.edu/~grout/encyclopaedia_romana/britannia/monsgraupius/calgacus.html Calgacus]</ref>
