One of the highlights today during my visit to the Germanisches National Museum in Nueremberg was this 16th century accountants table. Not only did it contain a double ledger on the table, but also a nine-men-morris game. Perhaps it was used to pass the time more pleasantly than with boring numbers. But it does give you some thoughts on the trustworthiness of the caretakers of your finances over the ages...
