Written by Lonsdale Ragg, an Anglican priest, this book is intended to share Dante Alighieri's perspective on many topics pertaining to what the author calls liberal principles — from political liberty to religious ones. Dante is well-known for his book The Divine Comedy, originally called Comedìa (modern Italian: Commedia) and later christened Divina by Giovanni Boccaccio, which is widely considered one of the most important poems of the Middle Ages and the greatest literary works in the Italian language.
