I’d stumbled onto the British Library’s “Treasures in Full” site yesterday, seeking information on 17th century staging. (Links to the articles I found are on the left, under Baroque theater.) Coincidently, Sandra Taylor on the Louis XIV Yahoo list mentioned the same site today, but called my attention to specific festival books published for the court of the Sun King. I went back and did a search, typing XIV into the searchbox, which revealed links to a number of Louis XIV festival books. Wonderful!
This one, of the L’Isle enchantée festival at Versailles the week of May 7, 1664 is my favorite. You can turn the pages to see one beautiful illustration after another.
