Hans Holbein the Younger (1497/98–1543) was born in Augsburg, matured artistically in Basel within the circle of Erasmus, and eventually settled in England as court painter to Henry VIII. *The Ambassadors* was commissioned early in his English period, during a diplomatic mission to London by the French ambassador Jean de Dinteville.

Dinteville stands on the left (aged 29) and his friend Georges de Selve, newly appointed bishop of Lavaur, stands on the right (aged 25). The two-tier shelf between them is not arbitrary: the upper tier carries celestial globes, sundials, and astronomical instruments, signifying heavenly knowledge; the lower tier carries a terrestrial globe, an open arithmetic book, a lute, and a flute, standing for earthly knowledge and the arts. One of the lute strings is broken — a detail commonly read as a reference to the discord of the Catholic-Protestant split (consonant with Erasmus's plea about a 'broken Christian harmony').

The painting's central novelty lies in the foreground. An odd, elongated shape at first reads as an indistinct smear; viewed from the right or slightly below, it resolves into a giant human skull. This *anamorphic* technique was part of the Renaissance fascination with the limits of optical perspective. The painting's original installation — probably on a staircase landing in Dinteville's Château de Polisy — would have presented this oblique view naturally as the viewer descended. The skull is a *memento mori*: a reminder that for all the power of scientific instruments, death has the last word.

The panel was acquired by the National Gallery in London in 1890. The 1996–97 restoration used X-ray analysis to study the lower layers and revealed Holbein's reworkings of an earlier composition. Today it is among the National Gallery's most-visited pictures; visitors typically stand in front, then walk to the right to make the skull resolve.
