“Tamen omnia hæc, pariterque eodem impellentia unus ac parvus admodum pisciculus, echeneis appellatus, in se tenet.  Ruant venti licet, et sæviant procellæ imperat furori, viresque tantas compescit, et cogit stare navigia:  quod non vincula ulla, non anchoræ pondere, irrevocabili jactæ…Fertur Actiaco marte tenuisse navim Antonii properantis circumire et exhortare suos donec transiret in aliam.…Tennit et nostra memoria Caii principis ab Astura Antium renavigantes.”  Plin. xxxii. 1.  The popular error was long lived. “Life is a voyage, and, in our life’s ways, Countries, courts, towns, are rocks or remoras.” Donne, To Sir Henry Wotton.
