A curious fact as to the lines in which Aratos refers to the
constellation Cassiopeia must here be noted.
Aratos versified “the _Phainomena_ of the astronomer Eudoxos, who
lived cir. B.C. 403-350.” It has often been pointed out that the facts
concerning the constellations which Aratos and Eudoxos record “are to
a great extent traditional and archaic, and belong to another and far
earlier epoch.” What is said of Cassiopeia is a case in point; for thus
the poet deplores her pride and its punishment at line 654 _et seq._--
“And now she, too, her daughter’s form pursues,
Sad _Kassiepeia_; nor seemly still
Show from her seat her feet and knees above;
But she head foremost like a tumbler sits:
With knees divided: since a doom must fall
On boasts to equal Panopê and Doris.”[123]
[123] _The Phainomena or “Heavenly Display” of Aratos_, _ub. supr._
Now in Eudoxos’ time and in his latitude, though Cassiopeia’s head did
by a few degrees extend into the southern heavens, yet her position was
not so deplorably ignominious as the poem would suggest. Three thousand
years earlier the pity for her expressed by Aratos would have been
more appropriate, for then her whole figure for observers in lat. 35°
N. would have been visible in the southern quarter of the sky, and her
feet, not her head (as at Lat. 23° N.), would have been on the zenith.
These considerations may lead us to suppose that the idea of
Cassiopeia’s pride, and the fit punishment of it--_i.e._, her reversed
position in the heavens, must have assumed form in _northern_ latitudes
almost at as early a date as the constellation figures were first
imagined in _tropical_ latitudes.
If this be so, it is indeed curious to find a legend which embodied
the _animus_ of astronomic rivalry 3500 B.C. handed down for thousands
of years, and repeated in what professed to be a somewhat scientific
treatise at a date between 400 and 300 B.C., when the astronomic facts
no longer tallied with those narrated in the legend.
As to Andromeda, the classic story describes her as the daughter
of Cepheus and Cassiopeia; but the constellation itself--except on
legendary grounds--might equally well have marked the beginning of a
solstitial year 6000 B.C., or of a non-solstitial and calendrical year
3500 B.C.
The terrible prevalence of human sacrifices in ancient times, and
at the solstices especially, may make us almost fear that the
representation of a chained human victim had its place in the sphere at
the earlier (solstitial) date.
