Certain of the instruments depicted are apparently set to indicate various dates, such as the birthdays of the sitters or important events in their lives, as pointed out by Mr. Dickes. The same instruments, together with the other objects, also represent certain of the Seven Liberal Arts—Music, Arithmetic, Geometry and Astronomy. The terrestrial globe is copied from Johann Schöner’s globe of 1523, to which about twenty names of towns have been added by Holbein, chiefly in France and Spain, selected by Dinteville as an epitome of the foreign relations of France in shaping which he had taken some share, the most important of these additions, as elucidating the identity of the chief sitter, being, of course, Polisy. The Lutheran hymn-book and the crucifix may be taken as symbolical of France’s religious diplomacy and the opinions of the two friends. The hope of religious union between the Roman Catholic and the Reformed Churches played a large part in the life of the Bishop of Lavaur. “To find means to promote that end was the object of his most earnest thought; to see it accomplished, the dearest wish of his heart.”[100] Dinteville, too, belonged to the liberal Catholic party in France, and shared the Bishop’s views. Mr. Barclay Squire first pointed out that the hymn-book in the picture was painted from a copy of Johann Walther’s _Geystliche Gesangbüchlein_, published at Wittemberg in 1524. The German arithmetic book was copied from a manual, _The Merchant’s Arithmetic Book_, by Peter Apian, published at Ingoldstadt in 1527. The badge of the order of St. Michael is worn by Dinteville without the collar of scallop-shells, and merely suspended from his neck by a gold chain. This was in accordance with the rules of the Order, which permitted it to be so worn when under arms, or when travelling, hunting, or when at home in private, or in other places where there was no company. Other details of the picture are equally interesting, more particularly the elaborate mosaic pavement, which Miss Hervey discovered to be an accurate copy of the well-known paved floor in the Sanctuary of Westminster Abbey, for the construction of which marbles and workmen were brought from Italy by Abbot Richard Ware in the reign of Henry III. This interesting discovery affords additional proof that the “Ambassadors” was painted in England. Footnote 100: Miss Hervey, p. 221. [Sidenote: THE ACCESSORIES OF THE PICTURE]
