The various yellows of Florence--the prevailing colours--are spread out nowhere so favourably as on the Pitti side of the river between the Trinità and the Ponte Vecchio on the backs of the houses of the Borgo San Jacopo, and just so must this row have looked for four hundred years. Certain of the occupants of these tenements, even on the upper floors, have fishing nets, on pulleys, which they let down at intervals during the day for the minute fish which seem to be as precious to Italian fishermen as sparrows and wrens to Italian gunners. The great palace at the Trinità end of this stretch of yellow buildings--the Frescobaldi--must have been very striking when the loggia was open: the three rows of double arches that are now walled in. From this point, as well as from similar points on the other side of the Ponte Vecchio, one realizes the mischief done by Cosimo I's secret passage across it; for not only does the passage impose a straight line on a bridge that was never intended to have one, but it cuts Florence in two. If it were not for its large central arches one would, from the other bridges or the embankment, see nothing whatever of the further side of the city; but as it is, through these arches one has heavenly vignettes. We leave the river again for a few minutes about fifty yards along the Lungarno Acciaioli beyond the Trinità and turn up a narrow passage to see the little church of SS. Apostoli, where there is a delightful gay ciborium, all bright colours and happiness, attributed to Andrea della Robbia, with pretty cherubs and pretty angels, and a benignant Christ and flowers and fruit which cannot but chase away gloom and dubiety. Here also is a fine tomb by the sculptor of the elaborate chimney-piece which we saw in the Bargello, Benedetto da Rovezzano, who also designed the church's very beautiful door. Whether or not it is true that SS. Apostoli was built by Charlemagne, it is certainly very old and architecturally of great interest. Vasari says that Brunelleschi acquired from it his inspiration for S. Lorenzo and S. Spirito. To many Florentines its principal importance is its custody of the Pazzi flints for the igniting of the sacred fire which in turn ignites the famous Carro.
