The order of precedence and chronological order of these Iliad scholia is D, A, bT, and other. Material in them probably ranges from the 5th century BCE (the D scholia) to as late as the 7th or 8th century CE (the latest bT scholia). The same scheme applies to the Odyssey, except that A scholia, mainly of the Iliad, are in deficit. There are no printed works publishing all the scholia on the Iliad and Odyssey. Only partial publications according to various principles have been possible.
