text: During the Renaissance, the city's development was driven by the silk 
  trade, which strengthened its ties to Italy. Italian influence on Lyon's 
  architecture is still visible among historic buildings.[32] In the late 1400s 
  and 1500s Lyon was also a key centre of literary activity and book 
  publishing, both of French writers (such as Maurice Scève, Antoine 
  Heroet, and Louise Labé) and of Italians in exile (such as Luigi 
  Alamanni and Gian Giorgio Trissino).
