hello, i have recently been studying astrology deeper than previously and i have come into contact with information regarding a 13th and 14th zodiacal sign.

now the 13th sign Orpheus i was somewhat familiar with, i hadn't studied it deeply but i atlas knew of it, though the 14th sign Cetus is completely new information to me though it seems with a bit of research that both signs do indeed date back to ancient Greece and have corresponding constellations in the heavens.

my question was to the validity of these signs in understanding the macro and microcosm. if these signs are true and do need to be accounted for this means that i am not a libra, and could have spiritual implications, thank you.
