Antidotus

Antidotus was an ancient Greek painter, mentioned by Pliny the Elder in his "Natural History"
Life.
Antidotus flourished about 336 BC. According to Pliny he was a pupil of Euphranor, and the teacher of Nicias the Athenian. He worked in encaustic.
Pliny says that "Antidotus, as a painter, was more careful in his works than prolific, and his colouring was of a severe style." He mentions three pictures by him in Athens: "a Combatant armed with a shield; a Wrestler, also; and a Trumpeter, a work which has been considered a most exquisite production."
Pliny is the only writer to have mentioned him.
