The 1482 edition of Ptolemy’s ‘Geographia’ is only the third atlas ever printed and one of the rarest of the Ptolemy editions. It was printed in Florence by Francesco Berlinghieri (1440-1501) at a time when the city was ruled by the Medici family headed by the great Lorenzo de’ Medici. The first printed edition of Ptolemy’s classical second century atlas was in Bologna in 1477. A Rome edition followed in 1478. What makes this printing unique is that they are the first and only ones to be printed according to Ptolemy’s original design, that being on a plane projection with equidistant longitude and latitude lines. Most other editions use a trapezoidal projection. The text is notable for being a metrical rhyming paraphrase of Ptolemy, and the first written in Italian. The engraving is believed to be the work of the great engraver Francesco Rosselli. As Woodward wrote ‘the roots of the map trade in the Italian states can be traced to Florence, where the enterprise centred around the painter and miniaturist Francesco Rosselli, probably the first entrepreneur to be successful in making an independent living from the print and map trade’. There is some question to that attribution by Hind as it appears that Rosselli was not in Italy from 1480-82.

This is one of the most desirable maps in the atlas being a fine example of Ptolemy’s depiction of the British Isles. Unlike the previous editions the lettering is in much finer engraving and for the first time inlets and bays are defined along the coast. The River Thames and the Severn Estuary can be identified for the first time.
