The Nautica Mediterranea is a book by Bartolomeo Crescenzio Romano, printed in Rome in 1601 by Bartolomeo Bonfadino. It is a treatise whose first chapter is dedicated to the construction of galleys and contains a clear description of the methods in use to pre-design the frames that were to be pre-erected over the keel, showing the narrowing and rising of the bottom marked on the turn of the bilge, in the Mediterranean tradition.
