Passage: The Valencian economy recovered during the 18th century with the rising manufacture of woven silk and ceramic tiles. The Palau de Justícia is an example of the affluence manifested in the most prosperous times of Bourbon rule (1758–1802) during the rule of Charles III. The 18th century was the age of the Enlightenment in Europe, and its humanistic ideals influenced such men as Gregory Maians and Perez Bayer in Valencia, who maintained correspondence with the leading French and German thinkers of the time. In this atmosphere of the exaltation of ideas the Economic Society of Friends of the Country (Societat Econòmica d'Amics del País) was founded in 1776; it introduced numerous improvements in agriculture and industry and promoted various cultural, civic, and economic institutions in Valencia. Question: Who in Valencia was influenced by the age of Enlightenment's ideas?
Gregory Maians and Perez Bayer
