Scientists have found what may be the oldest map of the universe ever made, and it has been sitting under our noses all these years, locked away in the pages of an old medieval book.
Experts believe this discovery may be related to Hipparchus, the famous ancient astronomer who lived more than two thousand years ago and helped pave the way for scientific astronomy. The reason this discovery is so remarkable is that the original text has not been lost; It’s buried under another text. Now, scientists are using X-ray technology to reveal what the naked eye cannot see. Old star catalogs are slowly being revealed one piece at a time.
We’re still in the early stages, but it’s getting very exciting.
The oldest traces of a lost star map are hidden beneath medieval text
As Scientific American reported, this achievement relates to a manuscript known as the Codex Climaci Rescriptus. On the surface, it looks like an ancient religious document. Experts say that this manuscript may contain part of some astronomical indexes that can be traced back to the Hellenistic era. These documents are called palimpsests.
During the Middle Ages, parchment was expensive, so old documents were scraped up and rewritten.
Thus, many ancient books were lost throughout the ages. In this particular case, one can only assume that an entire map of the night sky could be rewritten.What makes this discovery particularly amazing is the fact that it deals with science. What’s even more amazing is that new technologies may help uncover them again.
Ancient Greek ruins are hidden under the Codex Climaci Rescriptus
The manuscript was long thought to be purely theological in nature. But closer examination revealed faint traces of earlier Greek writing beneath the later Syriac script. These subtle marks indicated that the manuscript’s origin was much older.Historians suggest that the underlying text may not have been random notes but an organized star catalogue. Early analysis has already identified references to known constellations and astronomical measurements.The existence of such data indicates a highly sophisticated understanding of the night sky, much older than previously assumed for this manuscript. It also raises the possibility that important scientific knowledge has survived through layers of reuse and rewriting, which have been hidden in plain sight for centuries.
How scientists use x-rays to read hidden ancient texts
In order to uncover what remains underground, researchers are using advanced scanning techniques at the SLAC National Accelerator Laboratory.
This facility is equipped with a synchrotron particle accelerator, which produces extremely powerful X-rays that can penetrate matter without causing damage.This technology helps distinguish between the chemical components of different inks. Medieval ink has been determined to contain iron, while older text written in Greek is suspected to be composed of other chemical elements, such as calcium compounds.
This method allows the separation of text layers.So far, the results have been fairly positive. Several fragments containing Greek texts have been successfully discovered. Some even contain partial information about the stars and their coordinates.
Hipparchus and the origins of stellar cartography
If the fragments turn out to be authentic, they could be related to Hipparchus, one of the most important people who played an important role in ancient astronomy.
Hipparchus is said to be responsible for coming up with one of the oldest star catalogs recorded in the West.Hipparchus was known for his contributions to the study of the rotation of the Earth’s axis, also referred to as precession. His calculations were impressively accurate even without the use of telescopes and modern instruments. Specialists have suggested that if the star catalog he produced turned out to be the fragments they found, our perception of how much the ancients knew about the sky would change completely.
The manuscript still holds many secrets waiting to be scanned
It is still a relatively small project. Only part of the manuscript has been examined, and there are approximately 200 pages in the entire manuscript, many of which are scattered throughout the world.As researchers continue to work on scanning those pages they have access to, they are trying to recover parts that might shed some light on the missing parts of the sky. It is unclear how much of that map has been preserved in manuscript today, but even the progress made so far is enough to cause a stir. The idea that a star map written hundreds of years ago might finally see the light of day is quite astonishing, yet it is becoming increasingly scientific.The sky may have been hidden for much longer, but with each new scan, it gets closer to becoming visible again.
