Yikes, I had no idea there was such knowledge on the 'black arts' here!!
Scary stuff!!
Actually we have had discussions on these esoteric knives termed 'athame' about seven years ago, and discussions got pretty interesting. The term athame is thought to possibly derive from 'attame' (Fr.=to cut or pierce) and it is noted that 'athe' (Gk.=Godless), however there is no agreed upon etymological reference as far as I know.
Interestingly the variant term 'arthame' seems to derive from the term used to refer to the knife in a 1930's horror movie "The Master of Crabs" !
(I'm still choking on dust from dragging out these old notes from those discussions years ago!
Apparantly the concept of the athame is ceremonial, and supposedly its use is much like that of the Tibetan phurbu in ethereal sense. It is theoretically an extension of self and used to direct the flow of energy or will, to invoke or banish. It is used to guide energy from self to the circle etc. and so on in the complexities of these wiccan ceremonies. Naturally in earlier times there is likely some sacrificial use implicated, but those situations are avoided in most explanatory information.
As mentioned, I had noted that I had thought these decorated scabbards were to be viewed point up, but must admit that although I had seen some reference somewhere with comments to that effect concerning looking at the sword, I honestly cannot relocate that item. Actually, I simply considered the structure of the church and obviously the doors had to be shown at the wider part of the scabbard, while the peak of the church would narrow toward the tip or point. It would seem silly to think that the doors would be seen upside down, on the roof ?(reminds me of the kids game with interlocked fingers about the church and steeple, of course I always got it wrong and my people were on the roof!!
Also, in discussions of the sword, the blade is often termed the 'root' of the blade, thus at the hand, and grows upward. In edged weapon esoterica, the Indian katar is often decorated with the 'kundalini' flame, which originates at the root of the blade, and burns upward, thus the blade would be viewed point upward. I believe these were the basis of my comment.
In finally looking at the Holbein daggers I mentioned, the decoration is shown in linear, that is viewed sideways ,so it would seem there is no set manner in viewing a scabbard as I had suggested. I apologize for my assumption and for the unsupported statement.
Returning to the dagger, it seems that about mid 16th century, decorative sheath designs began to become popular, most notably the Holbein examples I have mentioned. Apparantly Hans Holbein (the younger) published his book "The Dance of Death" in Lyons c.1523, and created scabbards with macabre theme based on his drawings. Later other examples took scenes from Roman and Swiss history as well as Old Testament themes. It would seem that this decorative theme motif on daggers and sheaths extended through Europe, and this example, though certainly much later of course, is carrying out its theme from literary sources in the same manner.
