A main reason why events are so rarely foretold by Astrologers, is because the Art is yet but imperfectly discovered, for hitherto those that have been most excellent in it, being commonly old persons, have despaired to live to see the fortunes of children newly-born, and the Nativities of persons grown up, being uncertain, they scarce thought them worth so much labour. - Cardan Girolamo (1501-1576)
