This online publication offers the complete critical edition of Eustathius’ Commentary on the Iliad by Marchinus van der Valk, printed in 4 volumes by Brill (Commentarii ad Homeri Iliadem pertinentes ad fidem Codicis Laurentiani editi, 1971-1987), as well as a new critical edition of Eustathius’ Commentary on the Odyssey, edited by Eric Cullhed (University of Uppsala) and S. Douglas Olson (University of Minnesota). The latter includes an up-to-date standard text, critical, citation and source apparatus, and English translation. The work is still ongoing, but the preface and the commentary on books 1-4 (α – δ) are now available. Both editions follows the pagination of the sixteenth century edition by Nicolaus Majoranus.
