In 1983 the Larisa Museum received an inscribed stele, purporting to be from the farming area of Agia Triada. Even today, parts can be seen in this area of the fortifications of an ancient city, thought to be the Thessalian Skotoussa. The inscription comprises 154 lines, and is written in the Thessalian (Pelasgian) dialect; it dates from 197–185 BC. It is a decree of the city (which is now proved to be Skotoussa), and concerns the description of a zone inside and outside the city walls, which was to contain no privately owned land. The decree was passed as part of the reorganization of the defences of the city after the collapse of Macedonian supremacy in the region. The zone was defined in detail using as reference points the towers, distances between the towers, and other sections of the walls, as well as parts of the city adjoining the wall. The result of such a systematic body of cross-reference is a description of nearly the whole of the city's fortifications. Following a topographic survey of the Agia Triada region, and taking into account older surveys, a restoration of the course of the wall is attempted. Using the inscription as a guide, a comparison is made between the sections of the wall that are described, together with other place-names appearing in the inscription, and the surviving ruins at Agia Triada.
