I find it a wonder that the discoveries of Apollonius, a millennia and a half before the Renaissance, could reach out across time, freeing us from an era of geocentricism, into the age of space exploration. His text, inscribed on a piece of animal skin, endured and fell into the hands of Kepler, who, along with his contemporaries, gave us modern astronomy.
