Amazing talent of an American romanticist has been appeared in different genres. Having been the founder of an American novel, comic and satiric epopee, Irving concentrates his literary abilities mostly in the genre of literary portrait or so-called novelist-biographer. The gallery of literary portraits finishes with biographic novel “The Life of Muhammad”. The translations of P.V.Kiriyevski and L.P.Nikiforova are very famous. Today we can approve that exactly Irving opened Islam and “his own” Muhammad to americans.
