Archimedes' Heat Ray
Archimedes reportedly used a heat ray to burn attacking Roman ships during the siege of Syracuse. While often considered mythical, some historians believe it was possible given the technological advancements of the time. -
Claw of Archimedes
The Claw of Archimedes was a device used to lift and drop enemy ships during the siege of Syracuse. Its existence is disputed but remains a fascinating example of ancient ingenuity. -
Polybolos
The Polybolos was an ancient Greek repeating ballista that could fire multiple arrows in quick succession. Its exact design and functionality remain speculative. -
Artificial Petrifaction
Girolamo Segato invented a method for artificially petrifying human cadavers, significant for medical education and research. This technique was lost over time. -
Panjagan
The Panjagan was a projectile weapon or archery technique used by the later Sasanians to shoot a volley of five arrows. Its exact design and functionality are unknown.
Lost Medical Knowledge
Many ancient cures and treatments have been lost, highlighting the importance of documenting and preserving medical knowledge.
-
