Arcturus setting midnigtt 
Capella setting midnight 
The Little Mysteries, Eleusinian, are considered to have been celebrated about the 
I 9tb February, which exactly agrees with the appearance of Capella at midnight on 
the axis of this temple. . The orientation day of the solar Temple of Diana Braiironia 
at Athens has been shown to have been the 21st of the same month. 
At Athens there is a small temple having this kind of orientation lately discovered 
by the German archmologists in searching for the ancient Agora. It also points 
nearly north-west and south-east. This orientation appears to admit of a solution 
similar to that of the temple at Eleusls last mentioned, through Arcturus setting 
about B.c. 700, but I reserve the list of the elements as the local altitudes require 
confirmation. 
The last temple on the list is that of the presumed Sanctuary of Venus at Ancona. 
The commanding site occupied by the mediaeval Duomo is stated to have been that 
of the ancient temple, and there seems no reason to doubt this tradition. In that 
case the walls of the church would probably rest upon the old foundations. It seemed, 
therefore, worth while to examine their orientation, which gave for this angle 
223° 11' 23", which is equivalent to a northern amplitude of 46° 48' 37", and, com¬ 
bining this with the latitude and the usual altitude for a star, elements are obtained 
as below.
