This woodcut titled "Haemorrhous," depicting a mythological snake, exemplifies how early modern scientific texts incorporated fantastical elements alongside empirical observations. Created by designer Geoffroy Ballain and woodcut artist Jean de Gourmont in 1565 for Jacques Grévin's works on poisons and venomous creatures, this image demonstrates the complex relationship between mythological thinking and emerging scientific methodology in Renaissance natural history.

The Haemorrhous snake's inclusion in texts discussing natural poisons reveals how the boundaries between observed and imagined phenomena remained fluid in early scientific literature. Rather than representing failed empiricism, this integration reflects a worldview that understood nature as potentially containing wonders beyond everyday experience. The snake's name, suggesting connection to blood and haemorrhage, demonstrates how nomenclature itself often carried symbolic meanings that shaped understanding of natural phenomena.

The woodcut technique allowed for detailed visual representation in printed materials, playing crucial role in standardising and disseminating knowledge of both real and mythological creatures. This technological innovation transformed how information circulated, creating increasingly stable visual references that shaped collective understanding of natural and supernatural phenomena. The intricate execution of this particular woodcut demonstrates the era's commitment to precise visual documentation even of creatures whose existence was uncertain.

The woodcut's acquisition by the Plantin-Moretus Museum in 1876 represents another phase in its cultural evolution—from practical printing element to preserved historical artifact. This transition reflects changing attitudes toward early scientific materials, which came to be valued not just for their content but as evidence of evolving approaches to knowledge classification. The image thus provides valuable insight into how Renaissance culture navigated the complex relationship between observation and imagination in developing early modern natural history.
