I have noted as especially beautiful in the first room Nos. 4, 6, 12, 23, by Andrea; and 10 and 21, by Luca. These, by the way, are the Bargello ascriptions, but the experts do not always agree. Herr Bode, for example, who has studied the della Robbias with passionate thoroughness, gives the famous head of the boy, which is in reproduction one of the best-known works of plastic art, to Luca; but the Bargello director says Andrea. In Herr Bode's fascinating monograph, "Florentine Sculptors of the Renaissance," he goes very carefully into the differences between the uncle and the nephew, master and pupil. In all the groups, for example, he says that Luca places the Child on the Madonna's left arm, Andrea on the right. In the second room I have marked particularly Nos. 21, 28, and 31, by Luca, 28 being a deeper relief than usual, and the Madonna not adoring but holding and delighting in one of the most adorable of Babies. Observe in the reproduction of this relief in this volume-- how the Mother's fingers sink into the child's flesh. Luca was the first sculptor to notice that. No. 31 is the lovely Madonna of the Rose Bower. But nothing gives me more pleasure than the boy's head of which I have just spoken, attributed to Andrea and also reproduced here. The "Giovane Donna" which pairs with it has extraordinary charm and delicacy too. I have marked also, by Andrea, Nos. 71 and 76. Giovanni della Robbia's best is perhaps No. 15, in the other room. One curious thing that one notes about della Robbia pottery is its inability to travel. It was made for the church and it should remain there. Even in the Bargello, where there is an ancient environment, it loses half its charm; while in an English museum it becomes hard and cold. But in a church to which the poor carry their troubles, with a dim light and a little incense, it is perfect, far beyond painting in its tenderness and symbolic value. I speak of course of the Madonnas and altar-pieces. When the della Robbias worked for the open air--as in the façade of the Children's Hospital, or at the Certosa, or in the Loggia di San Paolo, opposite S. Maria Novella, where one may see the beautiful meeting of S. Francis and S. Dominic, by Andrea--they seem, in Italy, to have fitness enough; but it would not do to transplant any of these reliefs to an English façade. There was once, I might add, in Florence a Via della Robbia, but it is now the Via Nazionale. I suppose this injustice to the great potters came about in the eighteen-sixties, when popular political enthusiasm led to every kind of similar re-naming.
