About

The Summa was written by Saint Thomas Aquinas between 1265 and 1274. The supplement and appendices were probably compiled from Saint Thomas's commentary on the Fourth Book of the Sentences of Peter Lombard by his friend, Fra Rainaldo da Piperno.

The Summa was translated into English by the Fathers of the English Dominican Province in 1947 and is now available from many web sites.

The purpose of this site is to make the Summa as accessible as possible.
