Greco-Roman

Aratos

In front of him revolves the tragic Cassiepeia, not very large, but visible on the night of a full moon; [190] only a few zigzagging stars adorn her, giving her all over a distinct outline. Like to a key with which men attacking a double door barred on the inside knock back the bolts, [194] such is the appearance of the individual stars that together comprise her. She extends outstretched arms just from her small shoulders: you would say she was grieving over her daughter.

(Kidd 1997)

Eratosthenes
Hipparchus
Hyginus, Astronomica

Euripides and Sophocles and many others have said of her that she boasted that she excelled the Nereids in beauty. For this she was put among the constellations, seated in a chair [?]. On account of her impiety, as the sky turns, she seems to be carried along lying on her back. (Mary Ward 1960)
