Little is known about the author.
Content
The 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.
The author asserts that the mezzaluna, a gauge for narrowing created by dividing a half-circle into equal segments and then passing those points to a gauge, does not yield fair curves. He prefers the busca, which is made by dividing a line into the sequence 1, 3, 6, 10, etc., as the curves created are more compatible with the curvatures of the ribbands fore and aft of the tail frames.
