The Medicis commissioned art and patronized artists. By what mechanism was this achieved? Did someone literally just hand a bag of florins to an artist? I'm interested in the whole process, from asking for the work through to, I guess, estimates of cost, then actual transfer of funds/material/?
I'm looking for the physical method of fund transfer. As an example, at work today I might submit a request to purchasing or an expense claim. What was the equivalent and how exactly did it get paid out?
