The Greek astronomer Hipparchus wrote a star catalogue between the years 170 and 120 BC – however, the astronomical text has been lost for centuries. This has now changed, as a team of researchers has uncovered the partially-erased text in a medieval manuscript.
An Italian historian has discovered that an early 17th-century treatise on astronomy was actually written by Galileo Galilei under a pseudonym. He hid his name to avoid being caught up in a public dispute between the Papacy and Venice.
Japanese researchers investigated Byzantine texts from the 4th to 7th centuries to identify five total solar eclipses near the Eastern Mediterranean and improve the model of the Earth’s rotation over time.
A 900-year-old cosmic mystery surrounding the origins of a famous supernova first spotted over China in the year 1181 has finally been solved, according to an international team of astronomers.
Noel M. Swerdlow, a distinguished historian of science and the world’s foremost expert on Ptolemy and Copernicus, died July 24. He was 79.
In the year 1054 people around the world spotted a strange new light that shined during the daytime. What they were observing was a supernova.
While astronomical instruments could be as useful to the medieval person as Google Maps is to us today, you pretty much needed a whole degree in mathematics to figure out how to use them properly.
One of the most persistent myths about the Middle Ages is that this was a time when science slept, deliberately suppressed by the medieval church. The reality couldn’t be further from the truth. This week, Danièle speaks with Seb Falk about the amazing story of medieval science.
This book, a reworking of Ptolemy’s astronomical masterpiece, the Almagest, was written in the early 1460s by Georg Peurbach and Johannes Regiomontanus, two of the most important figures of fifteenth-century astronomy.
Nearly a millennium and a half ago, red light streaked the night sky over Japan.
Chronicles and narrative histories of the Early Middle Ages contain a number of entries relating to astronomical events and atmospheric phenomena.
We identified thirteen celestial phenomena (comet passages and total eclipses of the Sun) that may have been collected in the construction of the Ragnarök image among the ancient Norsemen
Strange atmospheric phenomena visible all over Europe in September 1465 are interpreted as the result of a volcanic dust veil, possibly originating from a re-dated eruption of Kuwae in Vanuatu, in the southwestern Pacific.
“Our manuscripts show practical knowledge, knowledge from antiquity carried through to the Middle Ages, and this is a great manuscript to further strengthen that aspect of our collection.”
“The idea for this study came about from the strong desire to challenge the common assumption and perceived lack of scientific enquiry in the early Middle Ages, or commonly referred to as ‘Dark Ages’. This was the spark that ignited the intellectual collaboration between a medievalist and an astronomer.”
Using thrones, tables, mantles, frescoes, and manuscripts, Benjamin Anderson shows how cosmological motifs informed relationships between individuals, especially the ruling elite, and communities.
Since lunar and solar parallax play a crucial role in predicting solar eclipses, the focus of this paper is on the computation of parallax.
1330. In this same year on the Ides of July at the 8th hour of the day, the Sun was so greatly obscured that of its great body only a small extremity like a three-night-old Moon was seen.
In his De luce (on light) he extends it to the origin of the Universe in what has been referred to as the ‘Medieval Big Bang’.
Dissatisfied with the problems of the geocentric system inherited from Claudius Ptolemy, Nicholas Copernicus began the change from geocentrism to heliocentrism.
This essay analyzes the astrolabe and its ability to transfer ideas and culture across traditional geographic boundaries, from the perspective of Europe in the Medieval and Early Modern eras.
It will be worth while in this investigation to inquire whether comets have the same nature as the planets and stars … A comet seems to have certain things in common with them: rising and setting, the same appearance, although a comet is scattered and extends farther. It is also fiery and bright. And so, if all planets are earthy bodies, comets will also have the same condition. ~ Seneca
This article examines the changing political landscape of Medicean Florence, from Cosimo de’ Medici (1389-1464) to his grandson Lorenzo the Magnificent (1449-1492), through the letters of the celebrated neo-Platonist philosopher Marsilio Ficino (1433-99).
A detailed examination of the themes, motifs and secrets held with Michelagelo’s masterpiece.
