Forum Vulcani: The Hot Springs at Pozzuoli

Hoefnagel employed a layered approach, first sketching the composition in black chalk before reinforcing forms with fine pen lines and brown ink. The use of laid paper provides a subtle texture that enhances the rendering of atmospheric steam and foliage. His meticulous line work and attention to scale reflect the emerging discipline of topographical drawing in the late Renaissance.

The drawing belongs to a period when Flemish artists increasingly documented natural phenomena for scholarly and collector audiences. Though the work’s early ownership records are sparse, it has been preserved within collections that value Hoefnagel’s contributions to natural history illustration, illustrating the broader European interest in accurate landscape recording during the sixteenth century.
