I found these symbols in my research on the Three Logoi:
They seem to originate from the Mayans. They are very much alike the symbols Steiner gives for the three Logoi:
See the original text in The Logos Walks the Earth.
They come from the research of Augustus Le Plongeon (1825-1906) of the Mayans:
He was influenced by Theosophy and introduced a suncross as the Third Logos, but without any word definitions as with the others.
He was a photographer and amateur archeologist, and well known for his many photographs from the Mayans. His interpretations was influenced by Theosophy and it gives many interesting commentaries.
James M. Churchward took the findings of Plongeon and replaced them to India and later to Tibet and used it to promote his ideas of Mu or Lemuria. There are interesting anecdotes and observations but he have a thesis he manipulates the observations to prove. If he had tried to prove Atlantis as the center of America, Europe and Africa instead he wouldn’t have had to manipulate the evidence.
Churchward gave these glyphs:
And he described the glyphs as:
Hun – The Creator is one.
Lahun, two – He is two in one.
Mehen, man – Together they created man, mehen.
Mehen is the physical man, Lahun is life in man and Hun is the Creator.
Plongeon wrote this on the Third Logos, Mehen:
The blue color is the skin of etheric beings as seen in the physical world. The Third Logos is the land, the Earth.
Churchward wrote this on the glyph of the Third Logos:
A glyph, generally a circle but sometimes oblong with two parallel lines drawn through its center dividing it into three parts as shown (Niven’s Mexican Tablet No. 2379), is a common universal symbol.
It is found among the cliff writings of our western states, in inscriptions on the Mexican Pyramid at Xochicalco, in the Maya writings of Yucatan. It appears in a writing on Inscription Rock, northeast Brazil near the boundary of British Guiana, and in other various American carvings. It occurs in the ancient writings of the Uighurs, Hindus, Babylonians and Egyptians.
The Second Logos incarnates again and again and Zarathustra was such an incarnation. He quite possibly incarnated under that name a number of times. The winged symbol are used for the Second Logos in different cultures, like with Isis in Egypt:
A little curiosum, the symbol for the Deathly Hallows from the seventh Harry Potter book is interesting in this connection.
The triangle represents the Invisibility Cloak, the line the Elder Wand
and the circle the Resurrection Stone.
The circle represent zero, the line represents one and the triangle represents three, the first three spiritual numbers. Two don’t exist, duality is an illusion. Zero is the First Logos, one is the Second Logos and three is the Third Logos.
The Resurrection Stone represents the First Logos, it really don’t take part in life on Earth. The Elder Wand represents the Second Logos, the absolute power. The Invisibility Cloak represents the Third Logos, the invisible net behind all of the physical reality, Indras Net.
