The legend of Circassian women was also repeated by legal theorist Gustav Hugo, who wrote that "Even beauty is more likely to be found in a Circassian slave girl than in a beggar girl", referring to the fact that even a slave has some security and safety, but a "free" beggar has none. Hugo's comment was later condemned by Karl Marx in "The Philosophical Manifesto of the Historical School of Law" (1842) on the grounds that it excused slavery. Mark Twain reported in "The Innocents Abroad" (1869) that "Circassian and Georgian girls are still sold in Constantinople by their parents, but not publicly."
