Astraeus's name, built on the Greek word for star, has occasionally been run together in later tradition with a distinct figure, Astraea, the goddess of justice and purity said in Greek and Roman poetry to have lived among mortals during the Golden Age before withdrawing to the heavens in disgust at human wickedness, where she was placed among the stars as the constellation Virgo, a story told most fully by the Roman poet Ovid in the Metamorphoses. The two names look and sound closely related in English, star-associated Astraeus and star-departed Astraea, and some later mythographic compilations link them loosely, occasionally treating Astraea as connected to or even descended from Astraeus, but the ancient sources for each figure develop along genuinely separate lines, Astraeus as a minor cosmogonic Titan fathering winds and stars in Hesiod's genealogical scheme, Astraea as a considerably later ethical and astronomical figure tied to ideas about a lost age of justice rather than to any Titan family tree.
The resemblance is almost certainly coincidental at the level of underlying myth, both names simply derive independently from the same Greek root for star, astron, rather than one figure being invented as a relative of the other, but the confusion is old enough and persistent enough in secondary literature that readers encountering either name should check carefully which figure a given source actually means: a minor male Titan who fathered the winds, or a distinct goddess of justice whose myth ends among the stars of Virgo rather than in Tartarus with the defeated Titans.
