Tehuti also known as Thoth was a great personality in ancient Egypt. Tehuti was deified by ancient Egyptians and he was accepted and respected by all societies in the Near East. He is mentioned as the source of knowledge and inspiration in all mystical and esoteric traditions in the Near East and Europe.
In ancient Egypt he was known as the scribe of gods (Neteru). During the Greek rule of Egypt, Tehuti was identified as Hermes of Greek mythology. In the Greek mythological description he was the dispatcher of divine messages from gods. Tehuti is also identified as the Hermes Trismegistus of Hermetica. Prophet Idris mentioned in Quran was most probably Tehuti. In Jewish esoteric tradition Tehuti is sometimes identified with the mysterious prophet Enoch.
Tehuti taught astronomy, architecture, geometry, medicine, metaphysics and spirituality to the ancient Egyptians. The books attributed to Tehuti became collectively known as “Hermetica”. These books were rediscovered in 15’th century Florence and helped to inspire the Renaissance.
For a summary of Tehuti’s spiritual teachings please see my other article.
Tehuti was always associated with the invention of writing. He is credited with the invention of the sacred hieroglyphic writing. This gives us clues as to the time period he lived. He must have lived about 6 thousand years ago around the time when the scripts were being invented. Early archeological research pointed to Sumerians as the inventors of writing. Sumerian (Cuneiform) script started as representations of numbers to do accounting. Some are of the opinion that Sumerians came from Elam which is located in the Iranian plateau. Some think Sumerians came from Central Asia through Anatolia. We simply do not know the origin of Sumerians. It is clear, however, that Sumerians traded with the Dravidian people who started the Indus valley civilization (Harrapa, Mohenjo-Daro).
Recent research points in the direction of the Indus Valley civilization as one of the earliest inventors of writing. P.R. Sarkar mentioned  that the oldest script was invented 6000 years ago and it is called Samalháptii script. From my careful readings of P.R.Sarkar’s comments I believe that the Samalháptii script originated in the Indus valley. Kharosthi and Brahmii scripts emerged much later. Brahmii script was used to write down the Vedas for the first time.
It is important to clarify that the symbolic representations of linguistic and mythological elements existed ever since the settlements started. The recent discovery of the earliest settlement in human history (11500 years ago) Gobekli Tepe in southeastern Anatolia is forcing the academics to revise their dates. P.R. Sarkar’s estimate of 6000 thousand years ago for the invention of writing now seems conservative. The carved symbols of communication existed, the formal scripts came later.
As in the invention of farming, the invention of writing proceeded almost simultaneously in the major centers where farming communities organized into cities. Another sign of this period is farming using irrigation techniques. This means Nile Valley, Mesopotamia, Indus Valley and the Yellow River civilizations. Each center developed a separate script. Much later, in Egypt the Hieratic script was invented. The scribes of ancient Egypt used the hieratic not the hieroglyphic script in their work. The hieroglyphic script was used in monuments and sacred texts only.
There are stories about Tehuti’s migration into Egypt. Many speculative texts say that he came from Atlantis. Since there is no evidence for Atlantis yet, I have to assume that it is fictional. If Atlantis existed it must have been an island civilization in the Mediterranean. If you examine the migrations of modern humans (Homo-Sapiens) from East Africa to Asia it is clear that the oldest human activity outside of Africa is seen along the coastal migration routes (Persia and India) and simultaneously in Nile Valley, Mesopotamia, North Africa, Anatolia, Greece, Mediterranean islands and Caucasus. The earliest modern humans in the Mediterranean area could be linked to the M35 Y-DNA marker which goes back 25 thousand years. If Atlantis existed in the Mediterranean, it must have existed between 25-10 thousand years ago.
Stories tell us that after the Atlantis island sank (perhaps due to volcanic activity) some people migrated to North Africa and Egypt and some to Greece and Ionia (Yanya) and another branch to Lebanon and Syria (ancient Phoenicians ). They may have carried their advanced civilization to these locations. The stories indicate that Tehuti was one of the leaders of the island people. Mediterranean origin of Tehuti is possible but it is hard to believe that an isolated island civilization existed between 25-10 thousand years ago. For me, 6000 years ago makes more sense because of the strong association between the invention of writing and Tehuti.
In Sanskrit Egypt was known as Mishradesha which literally means a kind of mixture between oriental and occidental. Mishra means “mixed” in Sanskrit. Desha means “country”. This implies that in Egypt people from different origins mixed. The clue from Sanskrit is that, culturally, Egypt was a mixture of East and West. The “West” probably refers to the culture of ancient people who came from the Mediterranean islands and “East” refers to the culture of M17+J2+J1 (Y-DNA markers) people. I also speculate that Dravidian people entered Egypt after the demise of the Indus Valley civilization. The original East African genetics and culture was always there we should not forget that. The magnificent civilization of ancient Egypt was founded by such a mixture of people between 6-5 thousand years ago. The later migrations of Semitic people around 3 thousand years ago, Persians around 2,600 years ago, Greeks 2300 years ago, Arabs 1700 years ago and Turks around 300 years ago all added to the cultural richness of this ancient land..
Egypt was already becoming a “mixed country” between 6-5 thousand years ago. Many languages were spoken in Egypt at that time. Two of those languages were the Proto-Indo-European and Indo-Iranian. The Proto-Indo-European originated in Anatolia around 15000 years ago and spread in all directions: 1. to the west towards Greece 2. to the north of Black Sea from Balkans 3. to the north of Caspian sea from Caucasus 4. to the south towards Egypt. Another language spoken in Egypt was the Indo-Iranian which was developed by the J2+M17 people on the Iranian Plateu at a later period between 10000 and 6000 thousand years ago.
When M17 people of Northern Caucasus and Western Central Asia moved into the Iranian plateau between 10000-8000 years ago they were speaking Indo-European or the Vedic language which evolved from the Proto-Indo-European. When they mixed with the J2 (the genetic marker that originated in the Eastern Mediterranean) people the language evolved into the Indo-Iranian. The Indo-Iranian language spread: 1. to the east towards Indus Valley and India 2. to the west towards Mesopotamia and Egypt.
These early languages were spoken in the lower (North) Egypt. The upper (South) Egypt retained its East African (Nubian or Ethiopian) character and Nilotic language. The cultural development started when the lower and upper kingdoms united and the Egyptian language emerged from a mixture of Proto-Indo-European, Indo-Iranian and Nilotic languages.
