Meanwhile the _S. Bernard_ was not paid for. Fra Bartolommeo priced it at 200 ducats, and the convent being the gainer by his works, took his own valuation. Bernardo offered only eighty ducats; the Frati were indignant, and called in the Abbot of the Badia as umpire; he being unable to move Bernardo, retired from office; then a council of friends was resolved on, in which Mariotto was for the painter, and Lorenzo de Credi for the purchaser; but this also failed. It was next proposed to submit the question to the Guild of Druggists (_arte degli speziali_), which included at that time also doctors and painters; but the convent, refusing lay judgment, took the offer of Francesco Magalotti, a relative of Bernardo, who priced it at 100 ducats, and the monks had to be satisfied. The dispute ended July 17th, 1507. [Footnote: Rosini, _Storia della Pittura_, chap, xxvii. p. 245, and Padre Marchese, _Memorie_, &c., vol. ii. pp. 42 to 45.] All writers agree as to the fact of Fra Bartolommeo's friendship with Raphael, but very few are decided as to its date. Raphael was in Florence in 1504, but then Fra Bartolommeo had not re-commenced painting, and would have no works in the convent to excite his admiration of the colouring. Padre Marchese, following Rosini and Padre Luigi Pungeleoni, asserts that this intimacy was during Raphael's second visit in 1506, when he might have seen the newly-finished fresco of _The Disciples at Emmaus_. It is undoubted that their intercourse was beneficial to both. Raphael studied anew Leonardo's principles of colour under Fra Bartolommeo's interpretation of them, and the Frate improved his knowledge of perspective and harmony of composition. It is said they worked together at some pictures, of which one is in France, and another at Milan; but there is not sufficient evidence to prove this. It is also thought that Fra Bartolommeo helped in the composition of Raphael's famous _Madonna del Baldacchino_, which is truly very much in his style. The year 1508 marks the Frate's first acquaintance with the Venetian school, which was not without its influence upon him. Frequent interchange of visits took place between the Dominicans in the different parts of Italy; and Fra Bartolommeo took the opportunity then offered him of going to visit his brethren at Venice.
