La decorazione delle chiese di Sant Pere de Terrassa, esempio dell'uso politico di monumenti tardo-antichi nell'altomedioevo.

The site of Sant Pere de Terrassa (Barcelona, Catalonia) is an exceptional monument and evidence of the existence of the episcopal see of Ègara between 5th and 8th centuries. The several studies carried out since the 90's until year 2011, allow us to know in depth both archaeological and technical facts concerning one of the most ancient witnesses of medieval mural paintings within the Iberian Peninsula for the referred period. The following paper aims to analyse the most recent information from our latest study on these paintings, which were promoted by Frodoinus, bishop of Barcelona, at the end of 9th century due to political reasons.
