In his paper ‘The wrong text of Euclid: on Heiberg's text and its alternatives', published in 1996, W.R. Knorr resuscitated the debate which had taken place in the 1880s between the orientalist M. Klamroth and the editor of Euclid's Elements, J.L. Heiberg. In nuce the debate concerned the fundamental question of which manuscript tradition of the Elements should be assigned textual anteriority: the Greek tradition or the Arabic tradition. Whereas Klamroth argued for the latter position, Heiberg, whose view became the (...) prevailing one, endorsed the anteriority of the Greek tradition. (shrink)
