Reconstruction of a clepsydra (water clock), invented by Ctesibius of Alexandria, c270 BC (1857)
Reconstruction of a clepsydra (water clock), invented by Ctesibius of Alexandria, c270 BC (1857). Ctesibius (fl270 BC) was an inventor and mathematician who initiated a tradition of great engineers in ancient Alexandria. None of his writings have survived, and his inventions are only known about from references to them made by others. This clock worked by water dripping at a constant rate and raising a float with a pointer. It was only superseded in terms of the accuracy of its timekeeping in the 17th century when Christiaan Huyghens showed how the pendulum could be applied to clocks

EDITORS COMMENTS
This print showcases the reconstruction of a remarkable invention from ancient times - the clepsydra, or water clock. Invented by Ctesibius of Alexandria around 270 BC, this engineering marvel was a testament to the innovative spirit of ancient Greece and Egypt. Ctesibius, an accomplished mathematician and inventor, left behind no written records of his work. However, references made by others have allowed us to understand the functioning of this extraordinary timekeeping device. The clock operated by allowing water to drip at a constant rate, gradually raising a float with a pointer that indicated the passing hours. For centuries, this ingenious creation remained unrivaled in its accuracy until Christiaan Huyghens introduced pendulum clocks in the 17th century. This photograph captures not only an ancient machine but also represents an important milestone in chronometry. The image transports us back to Alexandria during its golden age as a center for scientific discoveries and technological advancements. It serves as a reminder of how human ingenuity has always pushed boundaries throughout history. Through this monochrome engraving, we are reminded that even without surviving writings or personal accounts from inventors like Ctesibius, their contributions continue to inspire awe and admiration today. This print is not just an exploration into our past; it symbolizes mankind's ceaseless quest for knowledge and progress in every field imaginable.
