East edge of Trilithon upright No. 60 it can be seen by anyone 
standing there ; also from the middle of the inner face of upright 
No. 59 it can be seen by anyone who will stoop slightly for the 
purpose. For a huge triangular piece, some five feet high, seems 
to have been broken away from the base of the outer circle 
upright No. 5, apparently to enable the stone to be seen from 
that direction. It is with this second point of view that I have 
now to deal. 
The alignment from the South stone to No. 59, under the 
impending portion of No. 5, and grazing the East edge of 
No. 51, makes an angle with the East of 31° 59’ 28", and as ar 
is reckoned from the first point in Aries round through first 
North, then West, then South, we must deduct this quantity, 
31° 59’ 28", from 360°, in order to obtain the ar of the star that 
was at that time observed along this alignment. ‘The result thus 
obtained is 328° 0’ 32’. Let us suppose that this was the aR 
of o Andromede at the time we wish to determine, which as we 
shall see was 2,788 years ago. This star is commonly known as 
Alpherat or Sirrah from Sirrat, al farras, the horse’s navel, 
it having originally been quartered on Pegasus. It has also been 
called Rasalmarat, head of the woman.
