Argiope is a Parnassian nymph — in some accounts a daughter of the river-god Cephissus — who bore the minstrel Thamyris to Philammon. When Philammon would not receive her, she went pregnant to the Odrysae in Thrace, whence Thamyris is called Odrysian. She is distinct from other Argiope figures (Telephassa-alias, Eleusinian, Teuthranian).

I.Mother of Thamyris
Apollodorus names Argiope as the nymph who bore Thamyris to Philammon, the musician son of Apollo (or of other fathers in variants). Thamyris grows to challenge the Muses and is punished with blindness and loss of song — a myth that makes Argiope the maternal link between Parnassian nymphs and Thracian bardic fame.
Pausanias adds that she lived on Parnassus until Philammon refused to take her into his house while she was pregnant; she then settled among the Odrysae (Description of Greece 4.33.3).
II.Parnassus and Thrace
The double geography — conception or dwelling on Parnassus, birth or upbringing in Thrace — explains why Thamyris is called both Parnassian in art and Odrysian or Thracian in ethnography. Argiope herself has no separate cult narrative beyond this motherhood.
III.Other Argiope figures
Mythographers also know Argiope as another name of Telephassa (wife of Agenor), as an Eleusinian mother of Cercyon, and as a Teuthranian wife of Telephus. Those women are separate persons; this node is only the Parnassian mother of Thamyris.
