Thomas Mann's first great novel, written at the age of 25, is an epic study of decadence among the merchant families of Hamburg at the end of the nineteenth century.The novel is based on Mann's own experience as the son of a German merchant prince, but it goes far beyond his own experience in its sweep and comprehensiveness. The novel is an astounding, semi-autobiographical family epic.Mann portrays the transition of genteel Germanic stability and arrogance to a very modern uncertainty and fear.
