S. Calimero, to the north-east, is also Romanesque. S. Nazaro, close to the last, one of the oldest foundations, standing in the days of St. Ambrose, rebuilt in later centuries and again completely transformed by Cardinal Borromeo, has preserved some Romanesque features in its exterior. Within there are some old stained-glass windows of German workmanship. A very precious silver coffer, with beautiful reliefs of late Roman workmanship, is also kept here. Attached to the church is a sepulchral chapel, built for Gian Giacomo Trivulzio by Francesco da Briosco in 1518. The tombs of the great Marshal and of members of his family, with their recumbent figures carved upon them by sixteenth century sculptors, may be seen in it. S. Giovanni alla Conca, also a very ancient church and much favoured by Bernabò Visconti, has a fine thirteenth century façade, restored. A very ancient church, said to have been the first built in Milan, on the site of a temple to the Sun, is the little S. Babila, just opposite the Column with the Lion, which marks the place of the old Porta Orientale at the beginning of Corso Venezia. As seen now S. Babila is a complete restoration, very scientifically accomplished in the last few years, and presents within and without a very perfect model of a Lombard church of the early centuries after the 1000. Most of these early Milanese buildings have indeed to be accepted on the faith of the modern restorer, but for whom these interesting churches would still be vested in the hideous baroque disfigurements of the seventeenth and eighteenth centuries. S. Sepolcro, close to the Biblioteca Ambrosiana, is one of these. The towers, the crypt—studied with much interest by Leonardo da Vinci—and the exterior of the apse alone remained of the eleventh or twelfth century church, and these have been lately restored and a new façade built in appropriate style to replace the Borromean substitute for the original. The interior is quite spoilt. In the sacristy there is a Nativity by Gianpietrino, a characteristic work, with some infants of attractively soft contours, but curiously brown flesh colour in the foreground. Sta. Maria a Beltrade, off Via Torino on the west side, is of very ancient origin, but has nothing of interest left except a twelfth century bas-relief of rudest and most childish style upon the wall outside, representing the old Candlemas procession in which an image of Madonna was carried from this church to the Cathedral, a Christian substitute for the Pagan ceremony in honour of Cybele. Another ancient Milanese sanctuary, the Chapel of S. Satiro, built in 879, was restored in the Renaissance period, and incorporated with the Church of Sta. Maria presso S. Satiro.[14] Footnote 14: See Chapter XIII.
