While attending school in Lüneberg, J. S. Bach used to travel to Hamburg (50km away) to hear the organist of the Catharinekirche: J. A. Reincken. Marpurg describes how Bach, returning almost penniless to Lüneberg, once rested outside an inn; how someone threw two herring heads out on the rubbish heap; how Bach – a Thuringian, to whom fish were a delicacy – picked them up to see if any portion were edible; how he found that they contained two Danish ducats, and was thus able not only to have a meal, but also “to undertake another and a more comfortable pilgrimage to Herr Reincken.”
