 Due to the bitter controversies arising from the publication of the Politica, Lipsius decided to return to the Catholic Southern Low Countries, settling first in Spa and then Liège (1591–1592). Having re-embraced the Catholic faith of his youth, he moved in August 1592 to Louvain, where he accepted the chair of history at the university and the chair of Latin at the Collegium Trilingue. In this final period of his life he prepared his edition of Seneca and his treatises on Stoic doctrines and physics. He also continued to write on classical scholarship and political philosophy, publishing antiquarian treatises on the cross (De cruce, 1593), the Roman army (De militia Romana libri quinque, 1595), Roman fortifications and armaments (Poliorceticon sive de machinis, tormentis, telis libri quinque, 1596), the grandeur of Rome (Admiranda sive de magnitudine Romana libri quatuor, 1598), ancient libraries (De bibliothecis syntagma, 1602), the Roman goddess Vesta and the Vestal virgins (De Vesta et Vestalibus syntagma, 1605), as well as Monita et exempla politica (“Political Advice and Examples,” 1605), an extended historical-philosophical “mirror of princes,” intended as a sequel to his Politica. In addition, Lipsius, appointed Royal Historiographer in 1595, was asked to write devotional tracts in honor of the Holy Virgin of Halle and Scherpenheuvel, thus supporting the religious and political agenda of the Archdukes Albert and Isabella: the Diva Virgo Hallensis: Beneficia eius et miracula fide atque ordine descripta (1604) and Diva Sichemiensis sive Aspricollis, nova eius beneficia &amp; admiranda (1605).
