Marcus Trahius pavement was discovered in Santiponce in 1984.
It is made on opus signinum with red pigmented surface of and white marble inlaid tiles. At the bottom it presents an oblong carpet patchwork network on which is inscribed in two overlapping gussets, an inscription in Roman capital letter. The rest of the upper space is filled by a dense network of swastikas faced double T, all framed by an outer border of points.
The inscription says: M. Trahius C(aii) f(ilius) Pr(aefectus o –aetor?) Ap(ollini) [templum? aedem?] / de stipeidemq(ue) ca(ulas o -vit?) [d(e) s(ua) p(ecunia) f(acienda?) coir(avit)?] o [fieri/poni test(amento)?].
The translation is: "Marco Trahio, son of Cayo, who was well Praetor or prefect of Italica, saw to it that was built a temple (?) To Apollo, paid for by public subscription, and their corresponding gates, paid for by himself"
This important person belongs to one of the local aristocratic lineages, the Traii, and is the oldest known ancestor to date of Emperor Trajan.
