The text of Ovid's Metamorphoses is not as indisputably established as one might think. Many passages are still obscure or plainly corrupt. 550 manuscripts, 500 editions and reprints, as well as countless critical notes and works must be taken into account when trying to establish the most reliable text for new generations of readers. This volume provides a detailed line-by-line analysis of Book XIII and offers thereby an indispensable starting point for a new critical edition not only of this but also of other parts of the poem.
