The
Lesser Key, the
Munich Manual, Rudd, and Weyer further agree in ranking Valac as a president and attributing him with the power to locate, summon, and control serpents. The
Officium Spirituum similarly attributes Doolas with the power to give the summoner command of serpents as well as "household spirits," but it ranks Coolor and Doolas as princes instead of presidents. Valac is listed 62nd in the
Lesser Key (even by Rudd) and the 50th by Weyer, with either version claiming he leads 30 legions of demons (though some manuscripts say 38). The
Munich Manual describes Volach as controlling 27 legions of spirits. The
Officium Spirituum (depending on the manuscript) ranks Coolor as either 22nd (with no note of how many spirits he commands) or (in the copy found in the Folger Shakespeare Library) 22nd and commanding 13 legions of spirits. All extant and complete versions of the
Officium Spirituum list Doolas as 25th demon, commanding 20 legions of spirits. Rudd's version uniquely has Valac opposed by the
Shemhamphorasch angel Iahhel. A manuscript titled
Fasciculus Rerum Geomanticarum lists him as Volach. == In popular culture ==
