Diogenes Laertius X; R. D. Hicks (1925), PerseusDL

Each inventory follows the numbering of an identified edition. “Complete” refers to that edition and document type; it does not claim to cover every surviving document by the philosopher.

Four individually identified letters: the three doctrinal epitomes and the last-day letter. Numbers refer to Diogenes Laertius sections, not a universal letter numbering. Fragmentary correspondence and recipients mentioned elsewhere remain to be inventoried; this set is not claimed to be complete.
