"The ancient Ambrosian Basilica of St. Lawrence," founded according to tradition by a Florentine widow named Giuliana, and consecrated by St. Ambrose in the days of Zenobius, was entirely destroyed by fire early in the fifteenth century, during a solemn service ordered by the Signoria to invoke the protection of St. Ambrose for the Florentines in their war against Filippo Maria Visconti. Practically the only relic of this Basilica is the miraculous image of the Madonna in the right transept. The present church was erected from the designs of Filippo Brunelleschi, at the cost of the Medici (especially Giovanni di Averardo, who may be regarded as its chief founder) and seven other Florentine families. It is simple and harmonious in structure; the cupola, which is so visible in distant views of Florence, looking like a smaller edition of the Duomo, unlike the latter, rests directly upon the cross. This appears to be one of the modifications from what Brunelleschi had intended. The two pulpits with their bronze reliefs, right and left, are the last works of Donatello; they were executed in part and finished by his pupil, Bertoldo. The marble singing gallery in the left aisle (near a fresco of the martyrdom of St. Lawrence, by Bronzino) is also the joint work of Donatello and Bertoldo. In the right transept is a marble tabernacle by Donatello's great pupil, Desiderio da Settignano. Beneath a porphyry slab in front of the choir, Cosimo the Elder, the Pater Patriae, lies; Donatello is buried in the same vault as his great patron and friend. In the Martelli Chapel, on the left, is an exceedingly beautiful Annunciation by Fra Filippo Lippi, a fine example of his colouring (in which he is decidedly the best of all the early Florentines); Gabriel is attended by two minor Angels, squires waiting upon this great Prince of the Archangelic order, who are full of that peculiar mixture of boyish high spirits and religious sentiment which gives a special charm of its own to all that Lippo does.
