Abstract
The presentation of three previously unpublished fragments from a manuscript in the Egyptian Museum in Berlin allows us to return in detail to the Responsorum Libri of Aemilius Papinianus : to the stylistic characteristics of this casuistic work, to the reasons for its extraordinary success in Late Antiquity, and finally to the paratext which was intended to facilitate consultation and enable us to find certain specific responsa . The Berlin fragments also give us the opportunity to propose a correction of Otto Lenel's Palingenesia Iuris Civilis , and to question the elasticity of the criteria adopted by Papinian in the distribution of material.
