PTOKHEIA (or Ptocheia) was the spirit (daimona) of beggary.
She was a companion of Penia (Poverty) and Amekhania (Want of Resource). Her opposite numbers were Ploutos (Wealth) and Euthenia (Prosperity).
Nowhere stated (she is called the sister of Penia)
Aristophanes, Plutus 549 ff (trans. O'Neill) (Greek comedy C5th to 4th B.C.) :
"Penia: It's not my life that you describe; you are attacking the existence beggars lead.
Khremylos: Is Ptokheia (Beggary) not Penia's (Poverty's) sister?
Penia: Thrasyboulos and Dionysios are one and the same according to you. No, my life is not like that and never will be. The beggar, whom you have depicted to us, never possesses anything."
