Anonymous or attributed artists | Workshop
They are anonymous artists or teams that have been identified by historiographical studies, which have generally took into account the stylistic analysis of the works. In most cases, the term “master” has been used to elaborate a very definite stylistic personality and the term “workshop” to refer to a collective work structure, located in a concrete place or geographical area. It is possible that within the workshop is included also the master’s hierarchy. In addition, it is also used the term “school” to refer to a very particular way of working during a period or in a concrete geographical area.
