Late-Baroque Italian painter & printmaker in etching who was court painter to Charles II of Spain; _ I_R_A_O, but Charles II's court painter was Carreno
Carreno was indeed appointed as a court painter to King Charles II of Spain in 1669 Yet King Charles II had more than one court painter during his monarchy. Giordano was King Charles II court painter from 1692-1702.
Hope the above data is helpful to you hadrianjeffs.
Fabriano is a 15th century painter and King Charles II is from the 17th century. King Charles 1661-1700. Sure that is correct. Pretty certain that is is Giordano.
