Remnants of the Ancient World

Fotis Lindiakos

Who/What: Fotios Lykoudis, a Greek sponge diver captain from the island of Symi.

When: 1900–1901.

Context: While sailing, Lykoudis and his crew took shelter from a storm near the island of Antikythera. One of his divers discovered what appeared to be corpses on the seabed, which were actually ancient statues from a shipwreck dating to c. 60–50 BCE.

Connection: His crew’s accidental discovery initiated the first major underwater archaeological excavation and ultimately led to the recovery of the Antikythera Mechanism, making him central to the lecture’s narrative.

Antikythera Mechanism

Who/What: An ancient Greek bronze device composed of over 30 interlocking gears, widely regarded as the world’s earliest known analog computer.

When: Constructed around 100 BCE; recovered in 1900–1901.

Context: Found among artifacts in a shipwreck near Antikythera, the mechanism was initially a corroded lump of metal. Later study revealed it could model astronomical phenomena, including planetary motion and eclipse prediction.

Connection: The central subject of the lecture, it demonstrates that Hellenistic scientists possessed highly advanced knowledge of astronomy, mathematics, and mechanical engineering far earlier than previously believed.

Albert Rehm

Who/What: Albert Rehm, a German classical scholar specializing in ancient texts.

When: Early 20th century (after 1902).

Context: Rehm examined inscriptions recorded in a German-language catalog of the mechanism and identified references to Egyptian calendar months and numerical cycles.

Connection: He was the first to correctly interpret the mechanism as an astronomical calculator, laying the foundation for all later research.

Metonic Cycle

Who/What: A 19-year astronomical cycle in which 19 solar years equal approximately 235 lunar months.

Connection: The Antikythera Mechanism includes a dial that tracks this cycle, showing its practical use as a calendar and astronomical predictor.

Callippic Cycle

Who/What: A refined astronomical cycle lasting 76 years (four Metonic cycles).

Saros Cycle

Who/What: An 18-year, 11-day cycle (223 lunar months) used to predict solar and lunar eclipses.

When: Known in ancient Near Eastern and Greek astronomy.

Michael Wright

Who/What: Michael Wright in London.

When: Early 2000s.

Context: Conducted further mechanical studies and proposed that the mechanism included planetary gear systems to track planetary motion.

Connection: Improved earlier models and pushed the idea that the mechanism was even more complex than Price originally believed.

Allan Bromley

Who/What: Allan Bromley from Australia.

When: Late 20th to early 21st century.

Context: Worked on reconstructing the mechanism and collaborated on building a functioning model.

Connection: Helped demonstrate that the theoretical designs of the mechanism could actually work in practice.

Tony Freeth

Who/What: Tony Freeth and leader in modern Antikythera research.

When: 21st century.

Context: Led advanced studies using 3D X-ray tomography, revealing hidden inscriptions and internal structures.

Connection: His work confirmed that the mechanism included multiple dials (Metonic, Saros, Olympic cycles) and functioned as a detailed astronomical and educational device.

Antikythera Mechanism Research Project

Who/What: A modern interdisciplinary research team studying the mechanism.

When: 21st century.

Context: Utilized cutting-edge imaging technologies to analyze fragments and decode inscriptions, including what appears to be a user manual.

Connection: Produced the most complete and accurate understanding of how the mechanism worked and what it was used for.

Cicero

Who/What: Cicero.

When: 1st century BCE.

Context: Wrote about a mechanical device built by Archimedes that could model the movements of the heavens.

Connection: His writings provide historical evidence that complex mechanical astronomical devices existed in antiquity, supporting interpretations of the Antikythera Mechanism.

Archimedes

Who/What: Archimedes.

When: 3rd century BCE.

Context: One of the greatest ancient scientists, known for contributions to mathematics, physics, and engineering.
