. Bonner zoologische Beiträge : Herausgeber: Zoologisches Forschungsinstitut und Museum Alexander Koenig, Bonn. Biology; Zoology. Fig. 17: Plate from an unknown French book of the Eight- eenth Century. The illustrations of KOLB (1719; Fig. 4) have been redrawn and supplemented by "le Cerastes" from Tachard (1686; Fig. 13), itself derived form the original dra- wing of Claudius (Fig. 9). Another Geirnan illustrator of note was Johannes Schumacher, originally from Rodenburg (fide ROOK- MAAKER 1989; identity of this village is uncertain), who arrived in the Cape as a soldier in 1770. Schumacher prepared watercolors for Hendrik Swellengrebel, who visited the Cape during 1776-1777 and later illustrated the Gordon Atlas (Hallema 1951; Forbes 1965; Schutte 1982). The Gordon Atlas depicts zoological and other subjects observed or collected by Robert Jacob Gordon (1743-1795) during his explorations in southern Africa between 1777 and 1786 (Rookmaaker 1981; HowGEGO 2003). Rookmaaker (1980, 1989) reviewed the zoological drawings of Schumacher and identified the species he illustrated. Although GORDON himself noted a wide variety of reptiles in his accompanying journals, only some of the more conspicuous tortoises, lizards, and viperids were drawn by Schumacher: Chersina a/igulata, Psammohates tentorhis (Bell, 1828) (Fig. 18), Homopiis areolatus (Thunberg, 1787), Geoche- lone pardalis (Bell, 1828), Pelomedusa subrufa (Lacé- péde, 1788), Chamaeleo namaqiiensis, Bradypodion pumilwiu Agama atra Daudin, 1802, Agama hispida (Kaup, 1827), Varamts albigularis (Daudin, 1802), Bitis átropos (Linnaeus, 1758), Bitis cornuta, and Bitis cau- £/afc (Smith, 1849).. Fig. 18: Illustration of Psammobates tentoriiis by Johannes Schumacher from the Gordon Atlas. Schumacher's drawings, executed approximately a century after those of Claudius, are much more realistic and his images of chelonians are espe- cially well done.
