There were horsemen and fishermen, and members involved in animal husbandry. In the 7th century BC merchants at Este used bronze coins, while by the 3rd century BC silver money was in use, especially at Padua. Farmers cultivated grain and grapes. Artisans produced ceramic and bronze objects, and wove wool cloth. Artifacts show that among the sports enjoyed were boxing and boat races. Many archaeological excavations are still under way in the Veneto today at sites such as Este, Padua, Oderzo, Adria, Vicenza, Verona and Altinum. Studies are also being done on the vast influence of the Greeks in the Adriatic and their interaction with the Veneti, particularly focusing on the Euboeans, Phocaeans and Corinthians. Studies are also being done on Villanovan and, more significantly, Etruscan activity in the region and their strong links to the Veneti. Modern surveys on the Veneti and other Ancient Italic peoples, including the Venetic inscriptions from Este, were published by A. L. Prosdocimi, A. M. C. Bianchi and L. Capuis. Other tribes originally thought to have been Illyrians and shown to be actually related to the Veneti are: Histri, Carni, Catari, Catali, Liburni, Lopsi, Secusses, Venetulani.
