Francophones will be delighted to know that they can now access Aquinas’s complete oeuvre in French online at http://docteurangelique.free.fr/. Some of the texts also have the Latin in the left-hand column.
The site seems to have been around since 2004 but it has only recently completed the project of translating Aquinas’s opera omnia. The translation of Aquinas’s commentary on the second book of the Sentences, for example, was completed in 2011.
Many of the translations have not appeared in French before (e.g., the complete commentary on the Sentences) and others are new French translations made especially for the site (e.g., De ente et essentia).
