Rizzo used the term the "Master of the Leaf" to identify the dies engraved by this gifted artist. Rather than placing his own signature on the dies, this master engraver would mark his work with a leaf beside the head of Apollo. His engraving was important in the transformation of the designs that appeared on the coins of Katane to more naturalistic interpretations and was an influence on his contemporaries Euainetos, Choirion and Herakleidas.
