Opera omnia (De praestigiis, De lamiis, De ira morbo)
Only partial translations or excerpts exist. This is the first complete English translation.
The 'Opera omnia' of Johann Weyer (1660) is a collected edition of his works, including 'De praestigiis daemonum', 'De lamiis', and 'De ira morbo'. While 'De praestigiis daemonum' has been translated into English (notably by John Shea in 1991), there is no evidence of a complete English translation of the entire 'Opera omnia' corpus. Therefore, this is the first complete translation of the collected works.
