"Hesychius' lexicon is undoubtedly the most important Greek dictionary to survive from antiquity. [...] In short, this edition is an enormous improvement on Latte for scholars who have the prior knowledge needed to understand the extra information provided, as well as the motivation and interests to use that information."

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 and Cunningham (SGLG 11/3 and 11/4, 2005 and 2010). This revised edition of vol. 1 provides a more complete record of the readings of the unique manuscript, cites parallels from related works in the current editions, and takes account of the scholarship of the intervening years. A revised edition of the second Latte volume (to be SGLG 11/2) and a volume of indexes and addenda (to be SGLG 11/5) are planned.
