These two brief essays bridge the gap between the extensive discussion of the nuptial number in Essay 13 and the massive commentary on the Myth of Er that will follow in volume III of this series. Essay 14 contains a kind of appendix in tabular form that summarises the three arguments that the life of the just person is happier. Essay 15 opens with a similar tabular presentation of the main sections of Book X of the Republic.

We can delve no further than the Vatican manuscript (Vat. gr. 2197) into the history of these diagrammatic representations of the contents of the two essays, but it is striking that both appear on the same page (111r). The scholia to the part of the codex that remained in Florence have one somewhat similar tabular presentation of information but this summarises divisions to be found among the kinds of powers in Plato’s Laws. It does not provide a tabular summary of the content of Proclus’ text.1 Part of Essay 13 carries over onto 111r, so it seems integral to the version created by the ninth- or tenth-century copyist.
