In chronicling ancient art I must here diverge a little. I have already mentioned how closely painting was in the beginning allied with working in metals as well as with sculpture and architecture. It is thus necessary to write of a magnificent work in metal, the study and admiration of generations of painters, begun in the life of Giotto, and completed in two divisions, extending over a period of nearly a hundred years. We shall proceed to deal with the first division, and recur to the second a little later.
The old Italian cities. They were then the great merchant cities of the world, more or less republican in their constitution. They stood to the citizens, who rarely left their walls, at once as peculiar possessions and as native countries rather than as cities alone, while they excited all the patriotism, pride, and love that were elsewhere expended on a whole country--which after all was held as belonging largely to its king and nobles. The old Italian merchant guilds, and wealthy merchants as individuals, vied with each other in signalizing their good citizenship by presenting--as gifts identified with their names--to their cities, those palace buildings, chapels, paintings, gates, which are the delight of the world to this day. It was a merchant guild which thought happily of giving to Florence the bronze gates to the baptistery of San Giovanni or St John the Baptist, attached to the Cathedral. After some competition the gates were intrusted to Andrea Pisano, one of a great group of painters, sculptors, and architects linked together and named, as so often happened in Italy, for their place of birth, Pisa. Andrea executed a series of beautiful reliefs from the life of John the Baptist, which were cast in 1330, gilt, and placed in the centre door-way. I shall leave the rest of the gates, still more exquisitely wrought, till their proper time, only observing that the Pisani group of carvers and founders are supposed to have attained their extraordinary superiority in skill and grace, even over such a painter as Giotto, in consequence of one of them, Nicola Pisano, having given his attention to the study of some ancient Greek sarcophagi preserved at Pisa.
Passing for a while from the gates of St John of Florence, we come back to painting and a painter, and with them to another monument--in itself very noble and curious in its mouldering age, of the old Italians' love to their cities. Andrea Orcagna, otherwise known as Andrea di Cione, one of a brotherhood of painters, was born in Florence about 1315. His greatest works are in the Campo Santa of Pisa.
