Update after crash ;)

Dear Soup friends,

We had a big database crash, and the backups we had were corrupted.
The only working backup was from 2015.
We are working hard on getting some data out of the crashed database.

Please be patient!
Your Soup.io Team



Hallo Soup Freunde!

Wir hatten einen großen Datenbanken crash, und die Backups, die wir hatten waren Korrupt.
Das einzig funktionierende Backup war von 2015.
Wir arbeiten hart daran noch Daten aus der gecrashten Datenbank heraus zu bekommen.

Bitte bleibt geduldig!

Declinations in the Almagest: accuracy, epoch, and observers
by John C. Brandt, Peter Zimmer, and Patricia B. Jones
JOURNAL OF ASTRONOMICAL HISTORY AND HERITAGE Vol. 17 No. 3
http://www.narit.or.th/en/files/2014JAHHvol17/    


Abstract:  Almagest declinations attributed to Timocharis, Aristyllos, Hipparchus, and Ptolemy are investigated through comparisons of the reported declinations with the declinations computed from modern positions translated to the earlier epochs. Consistent results indicate an observational accuracy of ≈ 0.1° and epochs of: Timocharis, c. 298 BC; Aristyllos, c. 256 BC, and Hipparchus, c. 128 BC.  The ≈ 42-year difference between Aristyllos and Timocharis is confirmed to be statistically significant. The declinations attributed to Ptolemy were likely two distinct groups—observations taken c. AD 57 and observations taken c. AD  128. The later observations could have been taken by Ptolemy himself.

Oldest extant magnetic compass,
from iron meteorite, pin on left side (now bent up) originally pointing North, the engraved figure demonstrates the variation of the length of days over the twelve month of the year (1st row June to January, 2nd row July to December). The object was used as a mobile sundial suspended on a string.

(1st century CE; from the Villa of the Papyri, Herculaneum, now Museo Archeologico di Napoli, Italy; catalog entry: "Object ID #335" in: http://www.ancient-astronomy.org/webapplications/gordon/SundialNavigatorProject/CurrentVersion/index.html)

[Alternative interpretation: bronze plaque to register the curing and aging of ham (bearing no relation to sundials).]
