Polykleitos

Polykleitos also Polyclitus or Policleitus, flourished about 450-420 BC. He was the most celebrated sculptor in antiquity along with his contemporary Pheidias and he was born at Sikyon about 480 BC. They were both pupils of the famous Ageladas.
Polykleitos worked at Argos and later became head of the Argive school of sculpture. He was the most influential artist of all ages. For more than a hundred years, they will study him and replicate his work.
According to Pliny, "he along of human kind is deemed to have embodied the principles of his art in a single work". Pliny refers to his famous work "Canon" (Doryphoros) in which he set the ideal proportions of the human body. Other works of Polykleitos are the Diadoumenos whose best surviving copy is in the Athens museum, his colossal masterpiece of a seating Hera at Argos, made out of gold and ivory, was considered as equal to Pheidia's Zeus at Olympia. We can have an idea of this statue from Argive coins that show us the whole figure or her head.
Another work of Polykleitos is the Wounded Amazon.
