Czech Republic
The Kingdom of Bohemia, with Moravia, lay outside the Roman limes apart from a short-lived frontier camp in southern Moravia, so it has no provincial building inscriptions and its transactional record begins in the middle ages — and begins in silver. The Kutná Hora mines made Bohemia the silver power of central Europe, and from 1300 the Prague groschen, struck from that silver and counted sixty to the kopa or weighed against the Prague mark of 253.14 grams, circulated far beyond the kingdom; in 1520 the mines at Jáchymov produced the large silver piece that gave Europe the word thaler and eventually dollar. Bohemian sums are therefore usually stated in an actual circulating coin whose weight and assay have been measured from hoards, which puts them unusually close to metal. The archives match the coinage: the weekly building accounts of St Vitus Cathedral for 1372 to 1378, kept by a canon of the metropolitan chapter, survive as one of the fullest medieval records anywhere of what a cathedral lodge paid its master, its carvers and its stonecutters, week by week and job by job.
