Archivists Found the Oldest Recognized Map of the Stars Beneath a Christian Manuscript – #information
A duplicate of astronomer Hipparchus’ map of the celebrities was found beneath the Syriac textual content of John Climacus’ “Ladder of Divine Ascent,” a treatise written in round 600 CE, based on a information launch from the Washington, DC-based Museum of the Bible.
Students have lengthy identified about Hipparchus’ star catalog as a result of different historical texts made references about it—however their searches for the doc itself have been unsuccessful.
“The newly found textual content is a exceptional breakthrough that highlights the inventive use of multispectral imaging know-how to learn beforehand misplaced texts,” Brian Hyland, the museum’s affiliate curator of medieval manuscripts, mentioned within the launch. “It additionally attests to the accuracy of Hipparchus’s measurements.”
Cautious evaluation confirmed that the traditional parchment was reused a number of occasions—like old-school recycling.
First, within the fifth or sixth century, a Greek scribe copied Hipparchus’ “Star Catalogue.” Hipparchus labored as a Greek astronomer, geographer, and mathematician through the many years between 162 and 127 BCE. The early scientist is taken into account the daddy of trigonometry and one of many best astronomers in antiquity.
Then, within the tenth or eleventh century, a scribe at Saint Catherine’s Monastery at Egypt’s Mount Sinai recycled the older manuscript to write down one thing new, says the Museum of the Bible.
The scribe in Egypt will need to have gathered leaves of parchment, additionally known as vellum, from not less than ten completely different older manuscript, says the discharge.

However over time, the remnants of the scraped-off ink started to darken—so researchers realized the doc was a palimpsest, with layers of various texts all written on the identical materials.
The museum carried out multispectral imaging of the leaves within the manuscript in 2013, 2015, 2017, and 2018, says the discharge. Then they despatched the manuscript to Tyndale Home at Cambridge College to check the underlying textual content.
The researchers printed their findings this month within the peer-reviewed Journal for the Historical past of Astronomy.
Along with confirming that Hipparchus’ textual content was hidden beneath the Christian treatise, the researchers additionally discovered that Hipparchus’ measurements have been extra correct than these of his successor, the mathematician, and astronomer Ptolemy.
The Museum of the Bible was based by the Inexperienced household, the homeowners of privately held arts and crafts retailer Interest Foyer.
