This anecdote encouraged the much-discussed identifications of four known types of Roman marble copies of the wounded Amazon with sculptors of lost originals that may be dated to 430 BC on stylistic grounds. These types, each well represented by numerous Roman copies and heads, are identified with three of Pliny's five sculptors; a type derived from Phradmon has not been identified. Of these, however, only the identification of the Mattei type as deriving from Phidias's original is undisputed. The assignment of the Sciarra-type as deriving from Polyclitus's original and Sosicles-type as deriving from Kresilas's original (or vice versa), on the other hand, is unestablished, although having been discussed since 1897. The German scholar R. Bolnach has written a thorough form-analysis for the Sciarra/Polycletus and Sosikles/Kresilas pairings.
