This dataset comprises 68 images from a Greek manuscript edition of Ptolemy’s Geography containing many diagrams and coloured maps, and produced between the 1375 and 1425. The digitisation was sponsored by A. W. Mellon Foundation through the Pelagios Project. Due to UK copyright law they are technically in copyright until 2039. However, given the age of the manuscripts and their place of production the Library believes it highly unlikely a public domain release will offend anyone; more information can be found at: https://www.bl.uk/catalogues/illuminatedmanuscripts/reuse.asp
