Basilica della Santa Casa
Stephen Báthory sent Andrew to Rome to start negotiations about an alliance against the Ottoman Empire, and to secure Andrew's creation as cardinal. Andrew and his retinue left Kraków for Italy on 10 September 1583. He visited Charles Borromeo, archbishop of Milan, who was a highly respected prelate and regarded as a living saint for his piety in his diocese. After their meeting, Borromeo wrote a spiritual instruction to him. In Milan, Andrew also met Giovanni Botero who described him as an actual representative of anti-Machiavellianism. A Protestant retainer of Andrew, Ferenc Forgách, converted to Catholicism in the Basilica della Santa Casa in Loreto on 21 November.
