Gorgasus was an ancient Greek painter and coroplast, probably from Magna Graecia, who worked in Rome towards the end of the 6th century BC. His name is linked to that of Damophilus in the decoration of the temple of Ceres, on the Aventine Hill facing the Circus Maximus, and he is credited with the decoration of the temple's west side. His importance lies in bringing a Greek artistic idiom to Rome at a time when Etruscan art seemed to dominate the peninsula.
His technique combined painting with clay modelling: he produced terracotta acroteria and murals, and signed his works with epigrams. During the work, the oldest Etruscan decorative reliefs on the temple were removed, framed and reused. After the fire of 31 BC and the later restoration under Augustus, his works were preserved, although none can be securely attributed to him today.
The date of his death is unknown. The chronology of Damophilus, who may be the Himeraean artist who trained the sculptor Zeuxis, could place their activity somewhat later than the temple's construction, a point that remains debated.
