A hand-coloured engraving by Johann Sadeler I depicting the biblical scene of the Brazen Serpent, rendered in the Northern Mannerist style.

This hand-coloured engraving by Johann Sadeler I depicts the biblical narrative from the Book of Numbers, where Moses erects a bronze serpent upon a pole to heal the Israelites from snake bites. The composition is organised around the central vertical axis of the pole, which draws the eye upward toward the serpent. Surrounding this figure are various groups of figures in states of physical distress, reflecting the narrative of the plague. The artist employs the stylistic conventions of Northern Mannerism, visible in the elongated proportions of the figures and the dynamic, somewhat crowded arrangement of the scene.

The background features a series of tents, suggesting the encampment of the Israelites in the wilderness. The colour palette is applied with precision, using muted tones that distinguish the figures from the grassy terrain and the distant mountainous horizon. The engraving technique allows for fine detail in the musculature and the drapery of the garments, which are rendered with clear, controlled lines. The inclusion of Latin and French inscriptions at the base of the print provides the theological context for the image, a common practice in sixteenth-century print culture where such works were intended for both devotional and educational use.

Johann Sadeler I was a member of a prominent family of engravers from Brussels. His work often involved the reproduction of designs by other artists, though he was also a skilled draughtsman in his own right. This particular print demonstrates the technical proficiency of the Sadeler workshop, which was known for its contribution to the dissemination of religious imagery across Europe. The print retains the character of a book illustration, with its clear narrative focus and balanced composition, offering a view into the visual culture of the late Renaissance period.
