| Diagram of multi-staged rocket by Johann Schmidlap. The filename is misleading, erroneously attributing the picture to Conrad Haas.Haas was an influence of Schmidlap, but Schmidlap was the first to publish multistage rocket designs in print. The diagrams by Haas and by Schmidlap are shown side by side in  Doru Todericiu,  'Raketentechnik im 16. Jahrhundert', Technikgeschichte 34.2 (1967), 97–114 (p. 112) online copy at epizodsspace.no-ip.org/bibl/inostr-yazyki/nemets/technikgeschichte/1967/Todericiu_Raketentechnik.pdf| Künstliche und rechtschaffene Fewrwerck zum Schimpff 1| Johann Schmidlap| [{Image src='https://www.austria-forum.org/cc/images/slim/publicdomain.png' alt='Public domain' align='center' link='https://www.austria-forum.org/cc/public-domain-10.html' target='_blank'}]| Datei:Johann Schmidlap rocket.gif
