During the next ten years he seized every opportunity for profitable travel. In 1573 he accompanied Paul de Foix on an embassy, which enabled him to visit most of the Italian courts; he formed a friendship with Arnaud d'Ossat (afterwards Bishop of Rennes, bishop of Bayeux and a cardinal), who was secretary to the ambassador. In the following year he formed part of the brilliant cortege which brought King Henry III back to France, after his flight from his Polish kingdom. He also visited several parts of France, and at Bordeaux met Michel de Montaigne. On the death of his elder brother Jean (5 April 1579), who was "maître des requêtes" to the "parlement", his relations prevailed on him to leave the Church, and he entered the parlement and got married (1588). In the same year he was appointed "conseiller d'état". He served faithfully both Henry III and Henry IV, because they both represented legitimate authority.
