This book contains the extant tradition of Benvenutus Grassus' Treatise on the eye and six
philological related studies. The tradition in Latin (Metz Bibliothèques- Médiatèques MS 176)
is displayed with the four known versions in Middle English (Glasgow Glasgow University
Library Hunter MSS 503 and 513) London British Library Sloane MS 661 and Oxford Bodleian
Library Ashmole MS 1468) along with one in Provençal (Basel Öffentliche Bibliothek der
Universität MS D.II.11). The diplomatic transcriptions of the manuscripts are synoptically
arranged to ease the researchers' consultation and comparison. The philological studies deal
with the versions of the Latin tradition and with the common and diverging features of the
English vernacular tradition mainly in the Hunter MSS. Both the synoptic edition and the
philological studies are the result of a collaborative edition and joint research on Hunter MSS
providing a state-of-the-art approach to the treatises.
