Alexander Rivera, also known as Silas Auriens, is an independent writer and researcher whose work explores comparative mythology, Gnosticism, Hermeticism, biblical symbolism, the Apocrypha, and the Western esoteric tradition. Drawing from ancient texts and historical sources, he traces the recurring symbols, deities, and religious ideas that have passed from one civilization to another—often surviving under new names. He is the author of The Sun Lady Unveiled, The Laurel Turns Green, and the co-author of Baphomet: The Temple Mystery Unveiled, co-written with Tracy Twyman. He also publishes essays and research through The Megas Aeon on Substack.
