CORVUS
An
original group. When the god Apollo became
enamoured of Coronis, mother of the great doctor Æsculapius, he sent a crow
to watch her and report on her behaviour.
To be candid, the crow’s report was decidedly adverse; but Apollo bird
with a place in the sky! Corvus is
distinctive, since its leading stars from a quadrilateral. There are 4 stars above the 4th magnitude.
(Abbreviation: Crv).
