(Map of the British Isles from Ptolemy's Geography, 1486)
Reference: Folio 152
Published in 1486, this is the oldest surviving geographical record of Wales and is taken from Geographia, a treatise on cartography originally written in the 2nd century by the Greek geographer, Claudius Ptolemy. It is one of the earliest printed maps of the British Isles, and is the oldest item in the National Library’s map collection. No original copies of the work survive from the Roman period, only later versions exist, both manuscript (13th-14th century) and printed (15th-16th century).
