キリスト教綱要
John Calvin, the promoter of Protestantism and friend of Jean du Tillet the archdeacon of Angoulême, was forced to flee Paris in 1533 and took refuge in Angoulême in the caves of Rochecorail at Trois-Palis. He wrote some of his "Institutes of the Christian Religion" there which first edition was published in Latin in Basel in 1536.
