It was a finely drawn chart which even in its present state of washed out presentation has many attributes, but, obviously the chart has been reduced in size to 1395 x 910mm, and before any investigation into its actual geographical portrayal takes place there requires to be an investigation to determine to what extent it has been reduced and thus what is “missing” such that a correct appraisal of the chart can be undertaken, This has been achieved using the wind rose graticule and its setting out. This I perceive nobody has bothered about before!
Then the drawn chart is analysed and compared to other charts which numerous researcher’s state quite frequently is probably a copy of the Cantino Planisphere or its derivative but it can clearly be shown to be from a different source chart. Finally the vexed question of attribution and date is addressed from viewing the actual script on the chart.
The text is 8, A4 pages and contains 21, A4 diagrams (A3 originally).
The postscript contains 26 photographs which were supplied by Biblioteca Comunale Federiciana at FANO of parts of the chart and are an excellent aid to studying its content.

An atlas of 20 sheets plus two cosmological pages which form two complete (nearly) charts, one being a Portolan and the other a Planisphere. A peculiarity of presentation gives rise to a comparison, unfounded, to Vesconte Maggiolo 1511 Atlas, and the date must be assumed from the beginning of the cosmological information commencing January 1508. The data is presented as found including many Greek toponyms combined with Italian toponyms and also with the historical items included help conclude it is a Genoese product c1507.
