World's oldest complete star map, lost for millennia, found inside medieval manuscript In a remarkable discovery, historians have uncovered what is believed to be the world's oldest complete star map, hidden for centuries beneath a medieval manuscript. This ancient mapping, thought to date back to the 2nd Century BC, is attributed to the Greek astronomer Hipparchus, a key figure often recognized as the father of scientific astronomy.
The Discovery
The star map was discovered while examining photos of a palimpsest during the COVID-19 lockdown. The manuscript, housed in Saint Catherine's Monastery in Egypt's Sinai Peninsula, was originally a Christian codex. The researchers used advanced multispectral imaging techniques to reveal that beneath the religious text lay this significant astronomical chart. This document is particularly groundbreaking as it provides coordinates for the constellation Corona Borealis, dated to approximately 129 BC.
Importance of Hipparchus
Hipparchus, who lived from approximately 190 BC to 120 BC, made significant contributions to the field of astronomy, including the accurate modeling of celestial bodies and developing trigonometry. His catalog included roughly 850 stars, noting their positions and brightness, and he was the first to observe the precession of the equinoxes—realizing that the earth wobbles on its axis, which affects stellar positioning.
Methodology of Research
To unearth the hidden map, researchers captured numerous photographs across various wavelengths, allowing algorithms to detect the underlying text. They were able to confirm the coordinates match those found in other medieval manuscripts known to contain Hipparchus's original work, thus providing a concrete link to this ancient catalog.
Further Investigations
Researchers aim to enhance their scanning techniques to explore more of the manuscript's 146 folios which are currently displayed in the Museum of the Bible in Washington, D.C. There is hope that other fragments containing ancient scientific texts may also be lying hidden in such palimpsests.
