👉 Polysteganus was a Greek philosopher who is known for his work on the theory of steganography, which deals with hiding information within an image or text without the reader or viewer being aware of its presence. He proposed that images and texts could be disguised by creating a pattern in which the hidden message would appear to be completely random or even nonsensical. Polysteganus is often associated with his work "The Book of Stanzas," which was published in 320
