Poland
The lands of the Polish crown lay outside the Roman frontier, so Poland’s transactional record begins with the medieval town rather than with inscriptions. From the fourteenth century the unit of reckoning was the grzywna or mark, a weight of silver counted in 48 groszy, while actual payment ran in small silver coin — the Kraków grosz and half-grosz — and, for large sums, in imported gold: the Hungarian florin above all, later called the czerwony złoty or red złoty, alongside Venetian ducats. The złoty polski was never a coin but a money of account, fixed at 30 groszy in 1528, so any Polish sum obliges a reader to ask whether the florin named is metal or reckoning. What survives is unusually rich for a country so often fought over: Kraków’s council and court books run from the 1300s, the royal household accounts from the reign of Jagiełło, and the Hanseatic municipal archives of Gdańsk and Toruń are among the best in the Baltic. Kraków in particular kept its parish and guild papers, which is why the financing of a single altarpiece can still be read five centuries later.
