10. List of Maps and Portolans Used. 

 (The asterisk marks those illustrated here ; the references are given 

 by the dates.) 

 I may note that I do not give any names from Carignano and Petrus 

 Vesconte, 1300-1320. Some early maps of v?hich I have seen photographs or 

 facsimiles do not give many names. The great fishing-banks off the Irish 

 coast are sometimes shown. Dulcert, 1339, shows the three off Arklow ; 

 De la Cosa, 1500, the same ; the Kish Bank, off Dublin, and two towards 

 Ardglas. They are indicated by dots in Agnesi's map, 1 544, and by small 

 apparent islands in the maps of Freducci, 1497, and Calapoda, 1552. The 

 Upsal map alone of the first two centuries gives correctly, but, as usual, without 

 names, the ]\layo Islands — the Iniskeas, Davillaun, Achill, Achillbeg, Cliara, 

 'furk, Caber, and Shark, as well as Bofin. The map made for Henry II of 

 France is nearly worthless, as the copyist could not decipher most of the 

 names on his exemplar. The Voltius map is also careless. I give one of 

 the Ptolemy maps to show their character; the last is non-Ptolemaic, a 

 mere badly copied portolan.'

 1507-1516; the oldest map Tvith the name America, Martin Waldseemiiller (Illacomilus), ed. 

 Fischer and Weiser, and many others in the National Library. The Facsimile Atlas of Nordenskiold, 

 and the maps of Fischer, Alouzo de Santa Cruz (ed. Dahlgren), 1892 ; Fra Mauro, De la Cosa, and 

 Huldingham (facsimiles), and others, are to be found in the Library of Trinity College. I owe my 

 best thanks to Mr. T. W. Lyster and Mr. A. C. De Burgli for assistance in finding the resources of the 

 respective Libraries.
