The flourishing economy of Syracuse and the surrounding area during the Hiero's kingdom was founded in a rich farming production - as demonstrated by the unusual lex hieronica tax system, which collected tithes from agricultural production - based on wheat and more. Salt-fish output was also quite substantial and processed in many plants, extensive traces of which survive along the Sicilian coast. The increased financial resources were reflected in an intensive public building activity, as well as private too. The impressive urban reorganisation of Neapolis, as too the expansion of the urban grid, availed of skilled and well-coordinated workers. A rich craft production from workshops specialised in the manufacture of pottery and coroplastic, as well as in the toreutic art and goldsmithery, also revealed the influence of Alexandrian art and was shared with other local towns, particularly Kentoripa and Morgantina.
