On the west side of the tank at Bacalhôa is a wall nearly a hundred feet long, and framed with tiles. In the centre the water flows into the tank from a dolphin above which is an empty niche. There are two other empty niches, one inscribed _Tempora labuntur more fluentis aquae_, and the other _Vivite victuri moneo mors omnibus instat_. These niches stand between four medallions of della Robbia ware, some eighteen inches across. Two are heads of men and two of women, only one of each being glazed. The glazed woman's head is white, with yellow hair, a sky-blue veil, and a loose reddish garment all on a blue ground. All are beautifully modelled and are surrounded by glazed wreaths of fruit and leaves. These four must certainly have come from the della Robbia factory in Florence, for they, and especially the surrounding wreaths, are exactly like what may be seen so often in North Italy. Much less good are six smaller medallions, four of which are much destroyed, on the wall leading north from the tank to a pavilion named the _Casa da India_, so called from the beautiful Indian hangings with which its walls were covered by Albuquerque. In them the modelling is less good and the wreaths are more conventional. Lastly, between the tank and the house are twelve others, one under each of the globes, which, flanked by obelisks, crown the wall. They are all of the same size, but in some the head and the blue backing are not in one place. The wreaths also are inferior even to those of the last six, though the actual heads are rather better. They all represent famous men of old, from Alexander the Great to Nero. Two are broken; that of Augustus is signed with what may perhaps be read Doñus Vilhelmus, 'Master William,' who unfortunately is otherwise unknown. It seems impossible now to tell where these were made, but they were certainly inspired by the four genuine Florentine medallions on the tank wall, and if by a native artist are of great interest as showing how men so skilled in making beautiful tiles could also copy the work of a great Italian school with considerable success.
