Peter, in the portico of the Basilica of St. Peter's at Rome, which is now so mutilated and altered as to leave little of the original design. As an architect, Giotto attained considerable eminence, according to Milizia, and erected many important edifices, among which is the bell-tower of S. Maria del Fiore. The thickness of the walls is about ten feet; the height is two hundred and eighty feet. The cornice which supports the parapet is very bold and striking; the whole exterior is of Gothic design, inlaid with marble and mosaic, and the work may be considered one of the finest specimens of campanile in Italy. GIOTTO'S ST. FRANCIS STIGMATA In the church of S. Francesco at Pisa, is a picture by Giotto, representing St. Francis receiving the Stigmata,[A] which is in good preservation, and held in great veneration, not only for the sake of the master, but for the excellence of the work. Vasari says, "It represents St. Francis, standing on the frightful rocks of La Verna; and is finished with extraordinary care. It exhibits a landscape with many trees and precipices, which was a new thing in those times. In the attitude and expression of St. Francis, who is on his knees receiving the Stigmata, the most eager desire to obtain them is clearly manifest, as well as infinite love towards Jesus Christ, who, from heaven above, where he is seen surrounded by the seraphim, grants those stigmata to his servant, with looks of such lively affection, that it is not possible to conceive anything more perfect. Beneath this picture are three others, also from the life of St. Francis, and very beautiful." [Footnote A: Stigmata, signifies the five wounds of the Saviour impressed by himself on the persons of certain saints, male and female, in reward for their sanctity and devotion to the service.] GIOTTO'S INVITATION TO ROME.
