It can be inferred from The Masque of the Red Death that it occurred in the 14th century. The plague manifested for several decades in this century and showed up again in both the 15th and 16th century.

"The Masque of the Red Death," a short story by Edgar Allan Poe, is set during a time of plague and social isolation, which suggests it likely takes place in the 14th century, during the time of the Black Death. However, since Poe wrote the story in the 19th century, it can also reflect contemporary anxieties about disease and social disparity of that era. Thus, while the narrative is rooted in the 14th century, its themes resonate with the 19th century in which it was published.
