The New Student's Reference Work/Nemesis

Nem′esis, said by Hesiod to be the daughter of Night, was at first the embodiment of righteous moral feelings or of the conscience.  Later, Nemesis was regarded as the power which balanced the fortunes of people and taught them to reverence the immortal gods.  From this was evolved the latest conception, that of the avenger of wrong.  She was at first represented as a young virgin, and later as clothed in a tunic, sometimes with sword in hand and a wheel at her feet, or in a chariot drawn by griffins.  Several fragments of Pheidias’ statue of Nemesis were discovered in 1890, in the famous temple of Nemesis at Rhamnus, Africa.
