The Latin medieval commentaries of the Roman satirist Persius (AD 34- 62), gathered from obscure ancient material, are published here for the first time in critical editions of 3 of the 5 anonymous traditions. This project, serving also as a model for other ancient authors, can show the specific reception of a Roman author in different epochs, regions and centres of education, and supply a better basis for the reconstruction of the ancient and early medieval commentaries of Persius.
