2001 and 2002 Field Seasons in Lisbon


All equipment was supplied by Centro Nacional de Arqueologia Náutica e Subaquática (CNANS).

Since the work entailed the displacement and positioning of heavy timbers, the students were assisted by CNANS' staff and project director Paulo Rodrigues. A forklift was used to move the timbers around.

The 1/1 scale drawings were made with the help of a device developed at Texas A&M University's Nautical Archaeology Program by Taras Pevni, consisting of a laser pointer pen mounted together with a pen on a small stand that guarantees a perfect 90° angle between the drafting plan and the timber underneath.


Duration of the Work

The 2001 campaign lasted from June 1st to June 30th, and the 2002 campaign from June 1st to June 30th.


As mentioned above the work lasted from June 1st to June 30th of 2002.


Work Assigned

The objective of this field season was to produce a complete set of drawings of all pre-designed frames, at a 1/10 scale (Table II).

The methodology followed was defined by the principal investigator Paulo J. Rodrigues, and consisted of three steps.

The first step entailed the execution of drawings of both fore and aft faces of each frame at a 1/1 scale over plastic sheets at an orthogonal projection.  This work was completed with drawings of both upper and lower faces of each frame directly over their surfaces, obtaining extended, flattened drawings of these faces.

The second step consisted on the execution of 1/10 scale pencil drawings of each of the 1/1 scale drawings.  The upper and lower faces were projected to create orthogonal views compatible with the fore and after face's drawings. 

The third step was the execution of the final drawings.  The pencil 1/10 scale drawings were inked, scanned, and finished on a computer with a graphics program. 

In the final drawings each frame was represented in four views, as indicated in the figure below (Fig. 10). 

Since we have good reasons to believe that these frames were designed on the face that was afterwards placed to the side of the master frame, the "design face" placed below in the drawings - which carries the shipwright's marks - is the after face on the forward frames, and the forward face on the after frames.

All captions are written in French, because these drawings were intended to be included in Mr. Paulo J. Rodrigues' Thèse de Doctorat (the equivalent of a master's thesis) which was presented at Université de Sorbonne, Paris 1, in France, for the fulfilment of the requisites to obtain a master's degree under the direction of Dr. Eric Rieth.
