Gazophylacium Anglicanum

Gazophylacium Anglicanum is a dictionary of the English language first published anonymously in London in 1689; gazophylacium is a Latin word, borrowed from Ancient Greek γαζοφυλάκιον, meaning thesaurus.

Current scholarship attributes this work to Richard Hogarth and identifies it as a translation of Stephen Skinner's Etymologicon Linguae Anglicanae of 1671. The Gazophylacium Anglicanum was reprinted in 1691 as A New English Dictionary.
