1911 Encyclopædia Britannica/Dipoenus and Scyllis

DIPOENUS and SCYLLIS, early Greek sculptors, who worked together, and are said to have been pupils of Daedalus. Pliny assigns to them the date 580 B.C., and says that they worked at Sicyon, which city from their time onwards became one of the great schools of sculpture. They also made statues for Cleonae and Argos. They worked in wood, ebony and ivory, and apparently also in marble. It is curious that no inscription bearing their names has come to light.
