Discuss one aspect of Venice's cultural attributes dating to the 18th century, or it's government and the governing class as it evolved during those years; it's trade - what did it consist of; it's outer lands' involvements in the War of Spanish Succession, or anything pertaining to 18th Century Venice, - the Villas and estates on the mainland; trade, the Grand Tour; you can include a work of literature by writers such as Henry James, who wrote about Venice during his own time spent there -- maybe you can find a poet or other writer from that era?
