An exhibition celebrating Welsh author and cartographer Humphrey Llwyd (1527-1568) is taking place at the National Library of Wales: BBC News, press release. Among other things, Llwyd produced the first published map of Wales (rather than as a part of another map), the Cambriae Typus, which appeared as an addendum to Ortelius’s Theatrum Orbis Terrarum in 1573. The exhibition runs until the 31st at the Library in Aberystwyth; admission is free. The Library’s digital version of the map is available here.
