...Jim, reading the commentaries on the 29th Aethyr now --- and I see that you have already made the connection to the 4 Royal Stars! but now, in the 29th, the sequence is different --> Antares is on the east, Aldebaran setting [and a personal note - I was born at exactly such a moment!]...
and this is the 'natural' sequence really - because, when Fomalhaut rises for example, Antares culminates, Reguluts sets, Aldebaran is on the lowest point; etc.
-- so, I wonder how could it be and why that the ancient said Aldebaran guards the east and Antares west, and Regulus south, Fomalhaut north !!?...
back to reading now...
[ if there was a smiley depicting a starry night, I would use it now to express my overall experience of the book so far, but since there's not, I'll just keep silent...]
