The next group of engravings, which include the "Astrologer", very successfully interpret the mood of Venetian painting of the first decade of the century in the medium of engraving. It is this group that he is most famous for, and that also introduce his stipple technique. Stippling means engraving with dots or little flicks of the burin, rather than the normal lines. Campagnola is able to convey varying tone by different intensities of dots, rather than by techniques of hatching and cross-hatching usually necessary.
