Every day is a learning day. I've just read that scientists have used new imaging techniques to recover lost text from a document that showed part of Greek scholar Hipparchus star catalogue from between 162 - 127 BCE. One comment caught my attention:
" Even in the Bronze age, Myceanean Greeks were sailing all over the Eastern Mediterranean and the Black Sea. The whole point of the Trojan War was because Priam effectively cut access to the Black Sea. In the Greek dark ages, 1100BC to 700 BC the Greeks built colonies from Crimea to Spain. Pytheas, somewhere around 320 BC, sailed around Britain, got far enough north to see drift ice and sailed in the Baltic."
