These beautiful hand coloured copper plate engravings are from a rare work by Carl Gustav Jablonsky entitled Natursystem aller bekannten in-und ausländischen Insecten. It was one of the earliest and most comprehensive classifications of butterflies and insects according to the Linnaean taxonomy. Jablonsky (1756-1787) was also the private secretary to the Queen Elizabeth of Prussia. Sadly, he died at the age of 31 and his work was complete by another German entymologist Johann F. W. Herbst. Frame outer size 280 x 340 mm In mint condition. Extremely rare. A collectors piece.
