Death in Venice (German: Der Tod in Venedig) is a novella written by the German author Thomas Mann published in 1912. The work presents a great writer who visits Venice and is liberated, uplifted, and then increasingly obsessed by the sight of a stunningly beautiful youth.Tadzio, the boy in the story, is the nickname for the Polish name Tadeusz and is based on a boy Mann had seen during his visit to Venice in 1911.

As the story opens, he is strolling outside a cemetery and sees a coarse-looking, red-haired foreigner who stares back at him belligerently. Aschenbach walks away, embarrassed but curiously stimulated. He has a vision of a primordial swamp-wilderness, fertile, exotic and full of lurking danger. Soon afterward, he resolves to take a holiday.

After a false start in traveling to Pula on the Austro-Hungarian coast (now in Croatia), Aschenbach realizes he was "meant" to go to Venice and takes a suite in the Grand Hôtel des Bains on the Lido island. While shipbound and en route to the island, he sees an elderly man in company with a group of high-spirited youths, who has tried hard to create the illusion of his own youth with a wig, false teeth, make-up, and foppish attire. Aschenbach turns away in disgust. Later, he has a disturbing encounter with an unlicensed gondolier-another red-haired, skull-faced foreigner-who repeats "I can row you well" when Aschenbach orders him to return to the wharf.

Aschenbach checks into his hotel, where at dinner he sees an aristocratic Polish family at a nearby table. Among them is an adolescent boy of about 14 in a sailor suit. Aschenbach, startled, realizes that the boy is supremely beautiful, like a Greek sculpture. His elder sisters, by contrast, are so severely dressed that they look like nuns.

Later, after spying the boy and his family at a beach, Aschenbach overhears Tadzio, the boy's name, and conceives what he first interprets as an uplifting, artistic interest.

Soon the hot, humid weather begins to affect Aschenbach's health, and he decides to leave early and move to a cooler location. On the morning of his planned departure, he sees Tadzio again, and a powerful feeling of regret sweeps over him. When he reaches the railway station and discovers his trunk has been misplaced, he pretends to be angry, but is really overjoyed; he decides to remain in Venice and wait for his lost luggage. He happily returns to the hotel and thinks no more of leaving.

Over the next days and weeks, Aschenbach's interest in the beautiful boy develops into an obsession. He watches him constantly and secretly follows him around Venice. One evening, the boy directs a charming smile at him, looking, Aschenbach thinks, like Narcissus smiling at his own reflection. Disconcerted, Aschenbach rushes outside, and in the empty garden whispers aloud "I love you!"
