Sorok

Sorok () was a historical subdivision of Moscow in terms of parishes, used during 17-19th centuries. In the Russian language the word may beconfused with "cóрок" (with the first syllable stressed), which means "forty".
By a decision of the Stoglavy Sobor of 1551, Moscow was subdivided into 6 "soroks":
On average, at these times each "sorok" encompassed 45 parochial churches.
The term gave rise to a Russian saying (recorded e.g., by Vladimir Dahl in his "Sayings and Bywords of Russian People") "There are "sorok sorokov" of churches in Moscow" (meaning "multitudes of churches in Moscow"). It is sometimes mistakenly interpreted as 40 times 40, i.e., 1600 churches in Moscow, which is an exaggeration: in 1917 there were "only" 441 parochial churches and slightly over 200 home churches in Moscow.
At present, the Russian Orthodox realm is subdivided into eparchies, further subdivided into "blagochiniyes" ("blagochinny okrugs", благочиние, благочинный округ).
