This paper presents the results of analyses carried out on three decorative phases of the pres- bytery of the church of Santa Maria Antiqua al Foro Romano in Rome: the fourth-century AD mosaics setting bed; the Adoration of the Cross, dated to the papacy of John VII (AD 705–7); and the paintings in the apse of the Pope Paul I (AD 757–68) phase. The research allowed the characterization of the painting techniques, pigments, organic compounds and degradation products by means of a video microscope, optical microscopy, and μ-Raman and FT–IR spectroscopy, contributing to a better understanding of the changes in the techniques and materials used throughout the centuries in one of the most relevant medieval Christian monuments in Western Europe.
