* It will be observed that the orientation of this temple at Ephesus is nearly the same as that of 
Nike A})terosat Athens, and there is not much difference either in the latitude or in the apparent height 
of the mountain eastwards; but in this case the rising, and in the other the setting of Spica has been 
adopted. This choice has been influenced by arcbgeological considerations; and in this case the large 
amount of margin allowed for the star’s amplitude appears to be justified by the very -wide central inter- 
col umnations of this temple.
