The Basilisk of the Grand Duke of Tuscany

This black-and-white engraving shows a creature with the head, neck, and torso of a rooster, complete with a prominent wattle and a feathered crest, transitioning into a long, scaly serpent's tail. The figure stands on two bird-like legs with sharp talons. The creature is rendered with fine cross-hatching to define its feathers and scales, appearing in a profile view facing left.

This image appears in Athanasius Kircher's 'Mundus Subterraneus', a seminal work of 17th-century natural philosophy that attempted to reconcile burgeoning empirical observation with classical and occult traditions. The inclusion of this 'basilisk' illustrates the era's ongoing fascination with teratology and the limits of biological taxonomy.
