Happie Money

The Milanese Peter Martyr wrote in "De Orbe Noro" (1612)

"But it is very needfull to heare what happie money they use, for they have money, which I call happy, because for the greedie desire and gaping to attaine the same, the bowelles of the earth are not rent a sunder, nor through the ravening greediness of covetous men, nor terrour of warres assayling, it returneth to the dennes and caves of the mother earth, as golden, or silver money doth. For this groweth upon trees."
