The Liuro da Fabrica das Naus has been dated to 1580 and is the earliest surviving treatise on shipbuilding in Portuguese. It's author, father Fernando Oliveira had written a previous treatise in Latin, titled Ars Nautica. The Liuro is the theoretical work of a scholar and not the practical work of a shipwright. It is comprised of a clear text, with few illustrations, and is, unfortunately, incomplete. As it survived, it is divided into nine chapters. Father Oliveira defines the dimensions of the primary structural components of a ship - stem, stern post, midship and tail frames - as simple proportions of the length of the keel. He then describes the use of algorithms similar to the ones described by Timbotta - such as the mezzaluna or the incremental triangle - to calculate the narrowing and rising of the floor timbers in the central portion of the hull, between tail frames (almogamas), the first and the last of the pre-designed frames of a vessel.1
