The Pineal Gland( Eye of Horus )?

The Amazing Similarities of the Pineal Gland and the Eye of Horus!

The Eye of Horus, also known as the left wedjat eye or udjat eye, is a profound symbol in ancient Egyptian religion, embodying well-being, healing, and protection. It is closely related to the “Eye of Ra” (the right wedjat eye), with both serving as significant emblems in Egyptian mythology, bearing a striking resemblance to the pineal gland as it is situated in the brain.

The pineal gland was celebrated as the third eye in many ancient cultures.

An aesthetic and theory I have always found fascinating

The pineal gland is present in almost all vertebrates, but is absent in protochordates in which there is a simple pineal homologue. The hagfish, considered as a primitive vertebrate, has a rudimentary structure regarded as the "pineal equivalent" in the dorsal diencephalon. In some species of amphibians and reptiles, the gland is linked to a light-sensing organ, variously called the parietal eye, the pineal eye or the third eye . Reconstruction of the biological evolution pattern suggests that the pineal gland was originally a kind of atrophied photoreceptor that developed into a neuroendocrine organ.

Allegedly, Ancient Greeks were the first to notice the pineal gland( eventhough the eye of horus is has been scripted in ancent Egypt hieroglyphics from (3250) BC However accrding to the Greeks the pineal gland is believed it to be a valve, a guardian for the flow of pneuma. Galen in the 2nd century C.E. could not find any functional role and regarded the gland as a structural support for the brain tissue. He gave the name konario, meaning cone or pinecone, which during the Renaissance was translated to Latin as pinealis. In the 17th century, René Descartes revived the mystical purpose and described the gland as the "principal seat of the soul". In the mid-20th century, the real biological role as a neuroendocrine organ was established.
