In a recent posting on his Terra Umbra blog, cult filmaker Richard Stanley discusses his recent short film Mother of Toads, based on the Clark Ashton Smith story of the same name (and set in Averoigne, Smith's fictionalised version of medieval souther France). By the sounds of things, Stanley has also added additonal Lovecraftian elements to his retelling of the tale.
Of interest to readers of this blog is a mention of the George Hay Necronomicon (portions of which appear elsewhere on the Terra Umbra website). In relation to which Stanley claims there are those within Southern France's esoteric community who believe the Hay Necronomicon to be based on an earlier Cathar grimoire, namely The Book of the Seven Seals. If I recall correctly, elsewhere Stanley also claims that this may have been one of the treasures supposedly smuggled out of the beseiged Cathar castle of Montsegur in 1244 - an event which has come to have a central bearing on many recent grail/holy bloodline conspiracy theories. Stanley also mentions a 12th Century carving containing what he believes to be 'the seal of Eibon', inferring this as possible proof of The Book of Eibon's actual existence. I'm not sure where all this is going, but Stanley has also made allusions to Lovecraftian elements underpinning the mystery of Rennes-le-Chateau. Hopefully I'll be in a posiiton to provide additional commentary regarding this matter as I learn more.
