A substantial lexicon compiled in the fifth century CE is attributed to Cyrillus (or Cyril). It consists primarily of Biblical glosses, but there is also some material from the ancient scholarly tradition, including Atticist writings and scholia. Entries from this lexicon have been heavily interpolated into our version of Hesychius' Lexicon, but Cyrillus’ lexicon also exists independently in numerous manuscripts. Unfortunately most of the lexicon is unpublished. Drachmann's book is the single most important study of this document; in the second part Drachmann provides an edition of a few sections (words beginning with βα-, θα-, θε-, λα-, and λε-).
