The Venetian archives preserve considerable documentation on the trade of artistic icons between Venice and Crete, which by the end of the 15th century had become one of mass production. There is documentation of a specific order in 1499, of 700 icons of the Virgin, 500 in a Western style, and 200 in Byzantine style. The order was placed with three artists by two dealers, one Venetian and one from mainland Greece, and the time between contract date and delivery was set at only forty-five days. Probably the quality of many such commissioned icons was fairly low, and the dismissive term Madonneri was devised to describe such bulk painters, who later practised in Italy also, often using a quasi-Byzantine style, and apparently often Greek or Dalmatian individuals. Production of icons at these levels seems to have led to a glut in the market, and in the following two decades there is much evidence that the Cretan trade declined significantly, as the European demand had been reduced. But at the top end of the market Cretan icons were now the finest in the Byzantine world.
