A passage from the Benjamin Jowett translation of Plato's Meno—
" 'For in the ninth year* Persephone sends the souls of those from whom she has received the penalty of ancient crime back again from beneath into the light of the sun above, and these are they who become noble kings and mighty men and great in wisdom and are called saintly heroes in after ages ⋄ .' The soul, then, as being immortal, and having been born again many times, and having seen all things that exist, whether in this world or in the world below, has knowledge of them all; and it is no wonder that she should be able to call to remembrance all that she ever knew about virtue, and about everything; for as all nature is akin, and the soul has learned all things; there is no difficulty in her eliciting or as men say learning, out of a single recollection all the rest, if a man is strenuous and does not faint; for all enquiry and all learning is but recollection."

⋄ Jowett's note— "Pindar, Frag. 98 (Boeckh)"
Wikipedia authors like Protious, an alleged resident of Egypt and
creator of The Socrates Swastika , may enjoy a less scholarly account:
From Babylon A. D. (a 2008 film)— Toorop with Egyptian Sacred Scarab tattoo—
— and Toorop with Aurora (who may be regarded as "the soul" in the Meno passage above)—
Toorop's neck tattoo in the second image above is from a fictional book
described in the writings of H. P. Lovecraft.
As swastika-like sacred symbols go, I prefer St. Bridget's Cross.
