A detailed 1679 etching by Frans Ertinger depicting the mythological scene of the young Achilles being instructed by the centaur Cheiron.

This etching by the Flemish artist Frans Ertinger depicts the classical myth of the young Achilles receiving instruction from the centaur Cheiron. The composition is framed by an architectural border, featuring herms on either side that support a decorative floral frieze. The central scene shows the youthful hero mounted upon the back of his mentor, who holds a staff, suggesting a moment of tutelage within a pastoral setting. A hound rests near a tree in the background, while hunting implements, including a bow and quiver, are arranged at the base of the frame, referencing the education of a warrior.

Ertinger, active during the late seventeenth century, demonstrates a precise command of line and cross-hatching to define form and texture. The work reflects the period's interest in classical themes and the use of elaborate framing devices to contain narrative scenes. The figures are rendered with a focus on anatomical clarity, typical of the academic approach to mythological subjects during this era. The inclusion of the date 1679 in the lower margin confirms its production during the artist's mature period. This print serves as a representative example of the graphic arts produced in the Low Countries, where the tradition of copperplate engraving and etching remained a primary medium for the dissemination of classical iconography and historical narratives. The balance between the central mythological figures and the surrounding decorative elements creates a structured, formal presentation of the subject matter, consistent with the aesthetic values of the late Baroque period.
