[42] _Modern Painters_, vol. ii. "Of Imagination Penetrative." Now hath my life across a stormy sea, Like a frail bark reached that wide port where all Are bidden, ere the final reckoning fall Of good and evil for eternity. Now know I well how that fond phantasy, Which made my soul the worshipper and thrall Of earthly art, is vain; how criminal Is that which all men seek unwillingly. Those amorous thoughts which were so lightly dressed, What are they when the double death is nigh? The one I know for sure, the other dread. Painting nor sculpture now can lull to rest My soul that turns to His great Love on high, Whose arms, to clasp us, on the Cross were spread. (_Addington Symonds' translation._) The apse at the east end, or tribuna di San Zenobio, ends in the altar of the Blessed Sacrament, which is also the shrine of Saint Zenobius. The reliquary which contains his remains is the work of Lorenzo Ghiberti, and was finished in 1446; the bronze reliefs set forth his principal miracles, and there is a most exquisite group of those flying Angels which Ghiberti realises so wonderfully. Some of the glass in the windows is also from his design. The seated statues in the four chapels, representing the four Evangelists, were originally on the façade; the St. Luke, by Nanni di Banco, in the first chapel on the right, is the best of the four; then follow St. John, a very early Donatello, and, on the other side, St. Matthew by Ciuffagni and St. Mark by Niccolò da Arezzo (slightly earlier than the others). The two Apostles standing on guard at the entrance of the tribune, St. John and St. Peter, are by Benedetto da Rovezzano. To right and left are the southern and northern sacristies. Over the door of the southern sacristy is a very beautiful bas-relief by Luca della Robbia, representing the Ascension (1446), like a Fra Angelico in enamelled terracotta; within the sacristy are two kneeling Angels also by Luca (1448), practically his only isolated statues, of the greatest beauty and harmony; and also a rather indifferent St. Michael, a late work of Lorenzo di Credi. Over the door of the northern sacristy is the Resurrection by Luca della Robbia (1443), perhaps his earliest extant work in this enamelled terracotta. The bronze doors of this northern sacristy are by Michelozzo and Luca della Robbia, assisted by Maso and Giovanni di Bartolommeo, and were executed between 1446 and 1467. They are composed of ten reliefs with decorative heads at the corners of each, as in Lorenzo Ghiberti's work. Above are Madonna and Child with two Angels; the Baptist with two Angels; in the centre the four Evangelists, each with two Angels; and below, the four Doctors, each with two Angels. M. Reymond has shown that the four latter are the work of Michelozzo. Of Luca's work, the four Evangelists are later than the two topmost reliefs, and are most beautiful; the Angels are
