My exercise in identifying the number of years B.C. when 'the First Point in Aries' was at the heliacal stars listed for each glyph is no longer necessary. The point should now have been made - moving ahead in the year in a way corresponds to moving back in precessional time.
Furthermore, 'heliacal rising' can be defined in different ways, which makes my exercise rather meaningless:
... the time of the heliacal risings for stars is no universal measure, the definition is a variable. Lockyer (in his The Dawn of Astronomy) has described it:
| location of star |
time of observation |
relation to sun |
definition |
| rising (eastern horizon) |
morning |
true / cosmic |
sun rising too |
|
apparent / heliacal |
sun will soon be up |
| evening |
true / achronic |
sun setting too |
|
apparent / heliacal |
sun has just gone down |
| setting (western horizon) |
evening |
true / cosmic |
sun setting too |
|
apparent / heliacal |
sun has just gone down |
| morning |
true / achronic |
sun rising too |
|
apparent / heliacal |
sun will soon be up |
