“Behind”: the Akkadian word, arki, is abbreviated to ar2. The directions “behind” and “in front of” are defined in relation to the daily rotation of the sky which proceeds from east to west for an observer in the northern hemisphere, i.e. “behind” is “to the east of”, and “in front of” is “to the west of”.
Notice above this is from the OBSERVERS point of reference. Anyone in their astronomy program can see in the northern hemisphere by simply clicking the days forward will see the constellations move from east to west just as described above. And this Front and Behind designation is from the observers point of view.
This obviously causes problems for the -567 adherents. Again, they are caught in a problem when on the First day of the month that in -567 the moon is in Front of and not behind Taurus while at the SAME time Saturn is behind the Swallow.
Swallow is part of Pisces but not Piscis_Austrinus which is the original designation in line 2.
