"Liber MCXXXIX (Book 1139)" is listed in LIBER VIARVM VIAE sub figurâ DCCCLXVIII (Book 868) - “A graphic account of magical powers classified under the Tarot trumps.” It is mentioned as related to the "Seven Paths below the Magister Templi" - tied to ATU 6 - ז ZAYIN - "The Utterance of the Pythoness".
Liber MCXXXIX - The Utterance of the Pythoness (according to our knowledge) was never published.
One possibility is Liber VII: The Book of Lapis Lazuli : “...Being the Voluntary Emancipation of a certain Exempt Adept from his Adeptship. These are the Birth Words of a Master of the Temple.” Zayin=7.
