“Plato was initiated into the ‘Greater Mysteries’ at the age of 49. The initiation took place in one of the subterranean halls of the Great Pyramid in Egypt. The Isiac Tablet formed the alter, before which the Divine Plato stood and received that which was always his, but which the ceremony of the mysteries enkindled and brought from its dormant state. …” ~Thomas Taylor
“Westcott sums up his interpretation of the Tablet as follows:
‘The diagram of Levi, by which he explains the mystery of the Tablet, shows the upper region divided into the four seasons, each with three signs of the zodiac, … The central region he ascribes to the Solar Powers and the Planetary. In the middle we see above, the sun, marked Ops, and below it is a Solomon’s Seal, above a cross; a double triangle, Hexapla …”
“The Tablet of Isis was originally a table or altar, and its emblems were part of the mysteries explained by priests. … In his introduction to the Table, Kirsher summarizes ts symbolism thus: ‘It teaches, in the first place, the whole constitution of the threefold world—archetypal, intellectual, and sensible. …” ~Manly P. Hall
The Isiac Tablet
I have to admit that I had never heard of this tablet until I read this section of Mr. Hall’s book (The Secret Teachings of All Ages). It’s appearance and descriptions are fascinating. Also known as the Bembene Tablet or the Mensa Isaica, it is a large bronze tablet with enamel and silver inlays and most experts say it was probably made in Rome in the first century.
There are many interpretations of the tablet, including those who say it has no meaning at all but is just an interesting work of art. Some things are fairly clear just by looking at it. First, it is clearly divided into three horizontal sections. It may be that the top section is intended to represent the higher (spiritual) realms, the bottom section, the lower worlds of matter, and the center section representing the world of man who is caught between the two.
Most scholars doubt the claim that Plato was initiated on this table, but then most scholars doubt everything spiritual or esoteric.
In any case, the central figure of the whole tablet seems to be one of Isis with symbols around her indicating that this is clearly about the sun, and probably the spiritual sun. Several large birds are seen above Isis, which I suspect represent the Phoenix which is symbolic of the human soul and its journey.
Unfortunately, there seems to have been little study of the Isiac Tablet in modern times. It could very well be that some Roman simply created a work of art using random images from Egypt, still there does seem to be a significant number of spiritual symbols in this artifact (Isis, sun, bull, lion, dragon, wings, etc.) that a serious study of it is, in my opinion, worth considering.
