Ichneutai or Ichneutae (Ἰχνευταί), alternatively entitled Trackers or Searchers, is a satyr drama written by Sophocles. Until the beginning of the 20th century, only three short fragments of the play were known to exist (frr. 293-295 Nauck2), making it impossible to determine even the myth to which it referred, although scholars suggested variously the myths of the searches for Europa or for Glaucus. That situation changed in 1912 and 1927, when Arthur S. Hunt published volumes IX and XVII of the Oxyrhynchus Papyri, containing two papyri with large fragments of the play (P. Oxy. 1174 and P. Oxy. 2081a respectively).
