The Visconti, moreover, took great pains to advance learning and culture in their dominions. They founded the University of Pavia, the once celebrated school of jurisprudence there having long decayed, and richly endowed its chairs, and it was Galeazzo who started the famous library at Pavia, to which all students were allowed access. Bernabò was something of a scholar himself, and had studied the Decretals in his youth; but the anxiety of constant wars and the cares of State hindered him from doing all that he would willingly have done for the intellectual welfare of the capital. The bitter jealousy which prevailed between the two brothers divided them much in later years, though it could not disunite them in the face of their foes, and Galeazzo had left Milan and removed his Court to Pavia, though still keeping his share of the government of the capital. He died in 1378. His son, Gian Galeazzo, was delicate of constitution, of retiring habits, and much given to study. The gentleness with which he began to rule, remitting taxes and seeking to propitiate his subjects, excited the scorn of the grim Bernabò, who readily accepted the proposal of the young widower—Isabella de Valois having died—for the hand of his daughter Caterina, thinking thus to get an extra hold upon him. Little did the veteran prince suspect that this mild recluse, who was hardly ever seen out of his palace at Pavia, was the very quintessence of that subtlety, tenacity and ambition which had made the House of the Visconti the most dreaded in Italy. Gian Galeazzo’s genius for statecraft had been carefully trained by his father. While Bernabò regarded him as of little account, he was strengthening his position both at home and abroad by quiet diplomacy, and evolving mighty schemes in his mind, while he patiently waited the ripe moment for their accomplishment.
