Over the rest of the week we had some great sailing northwards through the islands to Zadar. Extraordinary how even on the smallest islands sometimes there are remarkable items of interest. On Prvic we learned about the 16th Century Croatian scholar and scientist Faust Vrancic who wrote in 1595 about parachutes and how tidal power could generate energy. He also found time to compile a 5 language dictionary. Equally wonderful was hearing a choir singing (unaccompanied) one evening as we passed the church. We sat in the evening sun listening - a moment of special peacefulness in a mad world.
