This book, Collegii Salmanticensis … theologicus Angelici Doctoris Diui Thomae complectens published in Madrid in 1637, is a collection of commentaries on the theology of the “Angelic Doctor”, Thomas Aquinas. It was originally owned by Narcissus Marsh and is now part of the Marsh’s Library collection. The first Irish Colleges were set up with the support of Irish Jesuit priest James Archer in Salamanca (where this book was written) and Madrid (where it was printed) during the late 16th century.
