The Platonic Solids are the five little white objects that lie in front of the Pedestal in most Chapters. They have a curious background and history. They were invented or discovered by Plato (429 – 347 BC) in ancient Greece around 380 BC. However they were first described by Pythagoras about 500 BC. Pythagoras (570 – 495 BC)was the guy whose theorem we all had to learn at school.
Who can remember it now? The five Platonic Solids are the only regular (equal sides) solids that can be constructed. There are only five Platonic Solids and these can be constructed from triangles, squares and pentagons with sides of equal length. It is not possible to construct a regular solid from a hexagon or anything with more sides. I can direct you to the full explanation of this statement but it involves complex, geometrical theory and having ploughed through it many times myself, I wonder if I am any better off, so I would simply say “Trust me I am a Royal Arch Mason.
Each body though represents one of “The four Elements and Sphere of the Universe”proposed by Plato. The four basic elements are Fire, Air, Earth and Water to which he added the Universe or everything else. Plato and his students argued that everything created by the Deity must be visible and tangible or it can’t exist – hence the importance of the solid shapes in ancient times
The Platonic Solids are explained as follows from the left to right, from the North in the Chapter.
There are also references and explanations about the relationship between the Triple Tau and the Seal of Solomon (Double Triangle) but these get even more complicated “Trust me I am…”
There is however one overriding and simple explanation to the presence of the Platonic Solids in our Chapters and that is they represent “Everything that God created”
Fire, Earth, Air, Water and the Universe, in its allegory Royal Arch Masonry is concerned with everything God created.
