Why was Fortuno having trouble breathing in the catacombs?

Answer 1

He wants to taste the amontillado (type of red wine) and he doesn't want Luchesi to taste it. Luchesi is Fortunato's competitor.

HOPE THIS HELPS :)

This story is really confusing and difficult to understand, I had to read it over 3 times to understand the whole story.

Answer 2

Fortuno was having trouble breathing in the catacombs due to the lack of fresh air and the accumulation of dust and debris, which can lead to respiratory issues like difficulty breathing. Additionally, the damp and enclosed environment of the catacombs may exacerbate breathing difficulties for some individuals.

Answer 3

Catacombs are often full of mold and fungus. There is not enough air circulation in many of them.
