Amalfi is first mentioned in the 6th century, and soon acquired importance as a maritime power, trading grain of its neighbors, salt from Sardinia and slaves from the interior, and even timber, for the gold dinars minted in Egypt and Syria, in order to buy the Byzantine silks that it resold in the West. Grain-bearing Amalfi traders enjoyed privileged positions in the Islamic ports, Fernand Braudel notes. The Amalfi tables (Tavole Amalfitane) provided a maritime code that was widely used by the Christian port cities.
Amalfi occupied a high position in medieval architecture; its cathedral of Sant'Andrea (St. Andrew, 11th century), the campanile, the convent of the Cappuccini, founded by the Amalfitan Cardinal Pietro Capuano, richly represent the artistic movement prevailing in Southern Italy at the time of the Normans, with its tendency to blend the Byzantine style with the forms and sharp lines of the northern architecture.
