posed of 15 distinct 
segments or so- 
mites, the head, 
formed of 7 anterior 
coalesced segments, 
counting as one. 
There are 7 free tho- 
racic segments, each with a pair of appendages, 6 abdomi- 
nal segments, and a small telson. The appendages of the 
tirst 3 abdominal segments are many-jointed bristly fila- 
ments, while the 3 posterior are styliform and serve as 
props when the animal leaps. The name is sometimes 
written, incorrectly, Ampithoe urAmphitoe. See cut under

curtain within the iconostasis. when drawn across 
it closes the opening left by the dwarf folding doors of 
the iconostasis, and entirely hides the altar and the cele- 
brant from the view of any one not in the sanctuary. Sev- 
eral times during the service the curtain is drawn back to 
allow the priest to come forward and read certain por- 
tions of the service while standing in front of the folding 
doors. As the iconostasis was for many centuries much 
more open in construction than at present, the amphi- 
thyra in early times formed almost as important a part of 
the barrier between the sanctuary and the rest of the 
church as the iconostasis itself. Erroneously written ain-

vessels of this form have been found In marble, alabaster, 
glass, and silver. The (topper of a wine-filled amphora was

covered with pitch or gypsum, and among the Romans

lids, and provided with bases enabling them to stand in- 
dependently, served commonly as ornaments among the 
Greeks, and were given as prizes at some public games, 
much as cups are now given as prizes in racing and athletic 
sports. The Panathenaic amphora? were large vases of this

and, filled with oil from the sacred olives, were given at 
Athens as prizes to the victors in the Panathenaic games.
