Galas is the myhtological founder of the Gauls. The Gauls inhabited Europe between the 5th century B.C. and the 5th century A.D. 

In Greek art, the term "Pergamene School" describes a type of Greek sculpture associated with the city of Pergamon in Asia Minor, during its golden age when it was ruled by the Attalid dynasty (241-133 BC). The style of sculpture championed by Pergamene artists is best seen as the leading edge of Hellenistic marble sculpture, during the period 200-150 BCE. It is characterized above all by highly expressive gestures, dramatic action-filled poses, exaggerated musculature and deep drapery folds, all of which helps to convey the pain, anguish and other emotions of its subjects.

These characteristics are exemplified in a votive group of statues commissioned by Attalus I (269-197 BCE), to celebrate his victory over the Gauls. Consecrated on the Acropolis of Pergamon, this group includes the famous staue of a Gaul killing himself and his wife. These and other similar Pergamene statues were later copied by Roman sculptors and are known as "Dying Gauls".
