School texts — Azione Romana

For centuries the Catholic schools taught by reading and expounding a few books: Aristotle's logic with Porphyry's Introduction, then his natural philosophy, metaphysics and ethics, Dionysius, Boethius, Peter Lombard's Sentences. They stand here in the order of the Paris arts statute of 19 March 1255: in the Latin the masters read, with St Thomas's commentary lectio by lectio, a public-domain English translation beside it, every passage with its Bekker number.
