But we go too fast: the church before the sacristy, and the glories of the church are Donatello's. We have seen his cantoria in the Museum of the Cathedral. Here is another, not so riotous and jocund in spirit, but in its own way hardly less satisfying. The Museum cantoria has the wonderful frieze of dancing figures; this is an exercise in marble intarsia. It has the same row of pillars with little specks of mosaic gold; but its beauty is that of delicate proportions and soft tones. The cantoria is in the left aisle, in its original place; the two bronze pulpits are in the nave. These have a double interest as being not only Donatello's work but his latest work. They were incomplete at his death, and were finished by his pupil Bertoldo (1410-1491), and since, as we shall see, Bertoldo became the master of Michelangelo, when he was a lad of fifteen and Bertoldo an old man of eighty, these pulpits may be said to form a link between the two great S. Lorenzo sculptors. How fine and free and spirited Bertoldo could be, alone, we shall see at the Bargello. The S. Lorenzo pulpits are very difficult to study: nothing wants a stronger light than a bronze relief, and in Florence students of bronze reliefs are accustomed to it, since the most famous of all--the Ghiberti doors--are in the open air. Only in course of time can one discern the scenes here. The left pulpit is the finer, for it contains the "Crucifixion" and the "Deposition," which to me form the most striking of the panels. The other piece of sculpture in the church itself is a ciborium by Desiderio da Settignano, in the chapel at the end of the right transept--an exquisite work by this rare and playful and distinguished hand. It is fitting that Desiderio should be here, for he was Donatello's favourite pupil. The S. Lorenzo ciborium is wholly charming, although there is a "Deposition" upon it; the little Boy is adorable; but one sees it with the greatest difficulty owing to the crowded state of the altar and the dim light. The altar picture in the Martelli chapel, where the sympathetic Donatello monument (in the same medium as his "Annunciation" at S. Croce) is found--on the way to the Library--is by Lippo Lippi, and is notable for the pretty Virgin receiving the angel's news. There is nice colour in the predella.
