The Intercalary or Embolimaan Year confifts of 
13 fuch Months. 
In each Cycle of ip Lunar Years, there are 12 
Common, and 7 Intercalary or Embolimaan Years, 
making together 237 Synodical Months. 
It was thought, at the time of the General Coun- 
cil of Nice, which was holden in the Year of our 
Lord 325, that ip Julian Solar Years were txaflly 
equal to fuch a Cycle of 19 Lunar Years, or to 237 
Synodical Months ; and therefore, that, at the End 
of ip Years, the New Moons or Conjundions would 
happen cxadly at the fame Times, as they did ip 
Years before : And upon this Suppofirion it was, that, 
fome time afterwards, the feverai Numbers of that 
Cycle, commonly called the Golden Numbers, were 
prefixed to ail thofe Days in the Calendar, on which 
the New Moons then happened in the refpedive 
Years correfponding to thofe Numbers it being 
imagined, that whenfoever any of thofe Numbers 
fhould for the future be the Golden Number of the 
Year, the New Moons would invariably happen on 
thofe Days in the feverai Months, to which that Num- 
ber was prefixed. 
Por i^Jjdian Solar Years contain 693P, 1 8, o, o,.o 
Whereas 2 3 y Synodical Months^ 
contain only . . . j ^939 I( 5, 3 Lf^^o 
This Difference amounts to a whole Day very 
nearly in 310.7 Years, the New Moons anticipating. 
But this was a Miflake :
