Hesychius' 5th(?)-century Greek lexicon is a very important survivor of ancient learning, including fragments of Greek literature and offering material, not yet fully evaluated, on patristic writings. The final critical edition was begun by Kurt Latte (Vol. 1, 1953 and Vol. 2, 1966, Copenhagen: Munksgaard; now out of print) and continued by Hansen (SGLG 11/3, 2005). Vol. 3, together with vol. 4 by Hansen and Cunningham (SGLG 11/4), provides for the first time a detailed report of the unique manuscript and a critical text, taking into account the relevant modern scholarship, and citing parallels from related works. A revised edition of the two Latte volumes followed (SGLG 11/1, 2017 and SGLG 11/2, 2019). A volume of indexes and addenda is planned (to be SGLG 11/5).
