This is one of the very few works published by the firm of Mount and Page that was not part of the extensive ‘English Pilot’ series. It was entitled ‘A compleat set of new charts on thirty-eight large plates: containing an accurate survey of the coast of Portugal and the Mediterranean Sea’. Alagna was an hydrographer from Messina, Italy. The title page was engraved by J. Larkin and it seems likely on stylistic grounds that the cartouches at least on the individual maps are also by him.
