With more than 50,000 glosses, the dictionary of Hesychios of Alexandria (approx. 500 AD), the most comprehensive dictionary of antiquity, giving posterity access to the massive collections of Hellenistic and Imperial lexicographers, is at the same time an extraordinarily important source for modern Greek lexicography and comparative linguistics. The epoch-making edition by Kurt Latte (Vol. 1: A-D 1953, Vol. 2: E-O postum 1966) is continued by Allan Hansen with Vol. 3: P-S; work has already commenced on Vol. 4 (T-W), and a 5th volume is in the planning stage with indexes and addenda to vols. 1-4.
