 There is an "altogether peculiar" charter surviving in a fifteenth-century copy, purportedly issued by Raymond of Galicia at Sahagún and dated, probably erroneously, to 1 April 1101.It refers to an "imperial army" ("exercitatus imperatorum") under Raymond's command probably left to guard the Tagus valley during Alfonso VI's campaign against Valencia.Two charters of 1112 refer to Queen Urraca as "empress" ("imperatrix"), including an original of 18 May.
