Quatre cartes desconegudes de l\'arquebisbe de Tarragona Antonio Agustin Albanell, en Faventia 12-13 (1990-91), pp. 337-352

The purpose of this work is to make known four still inedited letters from/to Antonio Agustin, who died in 1586 as archbishop of Tarragona, failing a complete edition of his collection letters announced from 1980. Some questions about Canon Law, Numismatics and Magdeburg Centuries are the main subjects about whose Agustin and his correspondents Zurita, de la Higuera, Zapata and del Frago write on this occasion. We have made also a short comment on them.
