  1. For those with an interest in ancient Egyptian history (and who doesn't?!), you may know of the Ptolemaic kingdom, an ancient Greek royal dynasty based in Egypt during the Hellenistic period. Founded in 305 BCE by Ptolemy I Soter, a general of Alexander the Great, it lasted nearly 300 years until the death of Cleopatra VII in 30 BCE: en.wikipedia.org/wiki/Ptolemai

    William E. Daehn has written a new book: Historical and Numismatic Timeline of the Ptolemaic Empire which looks quite interesting (though doesn't appear to be available outside the US yet). See this article in E-Sylum: coinbooks.org/v29/esylum_v29n3

  16. On a cloudy day in January, historian Ivan Malara sat in Italy’s National Central Library of Florence poring over seven 16th century printings of the ancient world’s most influential astronomy text.

    The pages belonged to The #Almagest, in which second century polymath Claudius #Ptolemy described his vision of an Earth-centered cosmos.

    As Malara flipped through the pages, he spotted something out of place.

    Someone had transcribed Psalm 145 on an otherwise blank page—in handwriting reminiscent of a very, very famous Tuscan astronomer.

    That book, Malara came to realize, had been extensively annotated by none other than Galileo #Galilei.

    Malara’s discovery, described in a paper now under review at the Journal for the History of Astronomy, promises new insights into one of the most famous ideological transitions in the history of science: the moment when #Earth was thrust from the center of our #universe.
