That was about noon. In the afternoon there was a calm, and Aschenbach rode to Venice under an intense sun. For he was driven by a mania to follow the Polish children whom he had seen with their governess taking the road to the steamer pier. He did not find the idol at San Marco. But while sitting over his tea at his little round iron table on the shady side of the square, he suddenly detected a peculiar odour in the air which, it seemed to him now, he had noticed for days without being consciously aware of it. The smell was sweetish and drug-like, suggesting sickness, and wounds, and a suspicious cleanliness. He tested and examined it thoughtfully, finished his luncheon, and left the square on the side opposite the church. The smell was stronger where the street narrowed. On the corners printed posters were hung, giving municipal warnings against certain diseases of the gastric system liable to occur at this season, against the eating of oysters and clams, and also against the water of the canals. The euphemistic nature of the announcement was palpable. Groups of people had collected in silence on the bridges and squares; and the foreigner stood among them, scenting and investigating. At a little shop he inquired about the fatal smell, asking the proprietor, who was leaning against his door surrounded by coral chains and imitation amethyst jewellery. The man measured him with heavy eyes, and brightened up hastily. "A matter of precaution, sir!" he answered with a gesture. "A regulation of the police which must be taken for what it is worth. This weather is oppressive, the sirocco is not good for the health. In short, you understand--an exaggerated prudence perhaps." Aschenbach thanked him and went on. Also on the steamer back to the Lido he caught the smell of the disinfectant.
