primatial privileges of the See of Arles were upheld as Leo I had defined them. At the same time, the bishops were admonished not to overstep their boundaries and to assemble in a yearly synod presided over by the Bishop of Arles. The metropolitan rights of the See of Embrun over the dioceses of the Maritime Alps were protected against the encroachments of a certain Bishop Auxanius, particularly in connection with the two Churches of Nice and Cimiez. Hilarius gave decisions to the churches of Hispania, which tended to operate outside the papal orbit in the 5th century. Bishop Silvanus of Calahorra had violated the church laws by his episcopal ordinations, and the pope was asked for his decision. Before an answer came to their petition, the same bishops had recourse to the Holy See for an entirely different matter. Before his death, Nundinarius, Bishop of Barcelona, expressed a wish that Irenaeus might be chosen his successor, and he himself had made Irenaeus bishop of another See. The request was granted and the Synod of Tarragona confirmed the nomination of Irenaeus, after which the bishops sought the pope's approval. The Roman synod of 19 November 465, held in the Basilica of Santa Maria Maggiore, which decided that Irenaeus, the nominated bishop, should quit the see of Barcelona and return to his former one, while the Spanish bishops were directed to condone the acts of Silvanus. This is the oldest Roman synod whose original records have survived. Construction projects Hilarius erected several churches and other buildings in Rome, for which the Liber Pontificalis, the main source for information about Hilarius, praises him. He also erected a chapel of the Holy Cross in the baptistery, convents, two public baths, and libraries near the Basilica of St. Lawrence outside the Walls. He built two oratories in the baptistery of the Lateran, one in honor of John the Baptist, the other of John the Apostle, to whom he attributed his safe escape from the Council of Ephesus, thus satisfying the question as to which saints the Lateran had been dedicated. Death Hilarius died on 29 February 468 and was buried in Basilica of St. Lawrence outside the Walls. His feast day is celebrated on 17 November.
