Iron Curtain

The first metaphorical usage of "iron curtain", in the sense of an end of an era, perhaps should be attributed to British author Arthur Machen (1863–1947), who used the term in his 1895 novel The Three Impostors: "...the door clanged behind me with the noise of thunder, and I felt that an iron curtain had fallen on the brief passage of my life".The English translation of a Russian text shown immediately below repeats the use of "clang" with reference to an "iron curtain", suggesting that the Russian writer, publishing 23 years after Machen, may have been familiar with the popular British author.
