Make up whatever legend you want, I guess.
There is one very distinctive play accesory
that comes with your Perseus action figure,
though, one that has both mythical and
scientific implications: the second brightest
star in the pattern, Algol. This star is a
variable star, and it seems likely that the
ancients could see it was changing in
brightness. Probably mystified by these
changes, they gave this star creepy names:
Algol is translated from the Arabic "Ras al
Ghul", or head of the demon.
The Israelites dubbed it "Rosh ha Satan" -
yeesh, Happy Halloween already. We've already
alluded to the less threatening stellar cluster
spread around Mirfak, the brightest star in
Perseus, but you might want to follow the
gentle arc of stars down his eastern side;
several of these blue-hot giant stars are among
the brightest in our galaxy. This star trail
also leads you down to the Pleiades, which is
over the border in Taurus.
