This striking woodcut from Ulisse Aldrovandi's encyclopedic works depicts a father and son afflicted with hypertrichosis, a condition causing excessive hair growth over the entire body. Identified as members of the famous Gonsalvus family, who were treated as 'wild men' in various European royal courts, these portraits exemplify the Renaissance era's scientific curiosity regarding the 'monstrous' and the limits of human nature.

This striking 12th-century illustration from an astronomical treatise personifies the Sun and Moon.

This detailed engraving reproduces a miniature from a 12th-century Psalter held in the Vatican Library.

This ornate frontispiece introduces Ulisse Aldrovandi's monumental work on cloven-hoofed quadrupeds, published in 1621. The architectural frame is populated by classical figures and heraldic symbols, including the coat of arms of the dedicatee, Paris von Lodron, Archbishop of Salzburg. The two powerful lions at the base, embodying 'Fortitude and Magnanimity,' reflect the noble virtues associated with both the patron and the scientific endeavor itself.
This woodcut depicts a 'Homo, ore & collo Gruis' (Man with the mouth and neck of a Crane), a monstrous hybrid from Ulisse Aldrovandi's works on natural history. The figure is shown in contemporary Renaissance attire, emphasizing the unsettling blend of the human and the avian. Such illustrations were part of a broader early modern fascination with 'monsters' and the limits of the natural world.

This intricate engraving serves as the author portrait for Ulisse Aldrovandi's monumental work on birds.

This elaborate architectural frontispiece serves as the title page for Ulisse Aldrovandi's monumental study of serpents and dragons. The design features a central title panel flanked by formidable dragons, topped by a coat of arms supported by putti, and grounded by a base containing symbolic medallions representing health and immortality. It exemplifies the fusion of scientific inquiry and allegorical art characteristic of early modern natural history publications.
This engraving reproduces a 15th-century panel painting from the Prague school, depicting Saint Augustine in the role of an Episcopal scribe. He is shown in full liturgical vestments, including a mitre, meticulously recording text in a large volume. The original work, characterized by its delicate relief and gilding, was part of the decorative scheme for the Chapel of the Castle of Karlstein.
