A short flight of steps leads to the =Ambulatory=, whose black-and-white marble screen, on the side toward the Choir, is not without dignity. The =sacristan= opens the locked =Chapels in the Ambulatory= (flamboyant), beginning at the steps on the R. or S. side of the Choir. You will find him in the Sacristy, in the N. Transept. Do not let him hurry you. The _1st chapel_ contains a tolerable triptych by F. Pourbus (son of Peter), with the Finding of Christ in the Temple for its central subject, and the Circumcision and Baptism on the inner wings. Notice in the last the conventional attitudes of the Baptist, the Saviour, and the angel with the towel, as in the Gerard David and all old examples of this subject: but the semi-nude figure undressing in the foreground is an unhappy innovation of the Renaissance. Many of the heads in the central picture are portraits: Alva, Charles V., Philip II., and Pourbus himself. On the outer wings is a good *portrait of the donor (Viglius) adoring the Saviour (1571). _3rd chapel._ Crucifixion, by Gerard van der Meire, of Ghent. On the left wing, Moses striking the Rock, symbolical of the fountain of living water, Christ. On the right wing, the Elevation of the Brazen Serpent, symbolical of the Crucifixion. This is a mystic “typical” picture, interesting only for its symbolism. Note the Flemish love of such subjects. The _4th chapel_ contains a good tomb of Cornelius Jansen and Willem Lindau, the two first bishops of Ghent (bishopric founded only in 1599) with fair recumbent figures of the early 17th century. _5th chapel._ Coxcie. Lazarus and Dives: a mediocre picture. Mount the steps to the =Upper Ambulatory=. The _6th chapel_ (of the Vydts family) contains the famous altar-piece of the =**Adoration of the Lamb=, by HUBERT and JAN VAN EYCK, to study which is the chief object of a visit to Ghent. See it more than once, and examine it carefully. Ask the Sacristan to let you sit before it for some time in quiet, or he will hurry you on. You must observe it in close detail.
