Prisoners behind bars opening on to a yard in Moscow being visited by men and women at Easter. Wood engraving, 1890.

"On certain specified holidays in the year, notably during Easter week, the public is admitted inside the prison-yards, and may then converse freely with relatives or friends, who happen to be behind the iron bars of a structure greatly resembling the bear-pits at the "Zoo". ... Our illustration is taken from one of the prisons at Moscow, where prisoners are detained until final judgment is passed on them, after which they are sent to other places to join the next transport to Siberia"-- The graphic, op. cit. p. 439
