Hieroglyphics of Horapollo: Book II.: CXVII. How a Man Previously Deranged in His Intellects, but Afterwards Becoming Sane
Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840]
When they would symbolise a man previously deranged in his intellects, but afterwards becoming sane, and bringing a degree of regularity into his life, they depict a SYRINX; for it is soothing, and calls to remembrance things that have been pleasurably done; and it produces a very regulated sound.
