One hundred years ago, J.K. Fotheringham famously derived the “accelerations” of the Sun and Moon from the reports of 11 classical solar eclipses. We review critically the reliability of these eclipse reports and rework his diagrammatic method, t

The reports of seven eclipses of the Sun and Moon in Bede’s Ecclesiastical History and its Continuation are investigated for their astronomical accuracy using modern-day calculations. The eclipses can all be identified from the given dates, which a

Using detailed knowledge of the Earth’s variable rotation, we conclude that the eclipse of BC 188 July 17 was total at Rome, and that Livy’s historical account of the darkness that befell the city in that year was due to this eclipse. This sets t

We investigate the date of observation of the Hipparchus eclipse using our latest measurement of historical variations in the Earth’s rotation to plot the tracks of the potential eclipses. We conclude that Hipparchus most probably analysed the ecli

An analysis of the tracks of total and annular solar eclipses crossing China reveals that most of the reports of such eclipses in the treatises in the dynastic histories from 206 bc to ad 1368 were very probably recorded at the capital by the court a

The errors in the timings of the Almagest occultations are investigated to ascertain what contribution they made to Fotheringham and Longbottom’s 1915 result for the (tidal) acceleration of the Moon. It is found that their result is quite close to

Analysis of historical records of eclipses of the Sun and Moon between 720 BC and AD 1600 gives a measure of the time difference, TT − UT = ΔT. The first derivative in time along a smooth curve fitted to the values of Δ T measures the changes in
