| To easly have a scale map of a certain zone for military purpose or just to measure a field in the past was used the Pretorian table (the support has gone lost). In fact with such an instrument the operation was fast and with a relative great precision. The tool is incomplete, because a brass bar fixed in the hole near one of the vertexes has gone lost. This piece (the graphometer) was used at the same time to draw lines on a paper sheet placed on the table and to work as goniometer.
