That's what some church faithful believe.

In Naples, Italy, three times a year, a vial of dried blood said to come from the city's patron saint, San Gennaro, is put on display when it liquefies.

It is known as the Miracle of San Gennaro, but when it fails, some residents see it as a sign of disaster to come.

On Wednesday, despite hours of praying, Priest said the blood was rock solid.

He started.

Scientists say the substance inside the sealed vial appears to be dried blood, but they cannot explain why it sometimes turns into liquid on sometimes does not.

However, it's not the worst scenario.

People get particularly nervous if the blood does not liquefy on the saint's feast day, September 19th.

The other two days occasions in December and May are not seen as being a bad.

On Wednesday, the city's cardinal Christians, Joosep, told the faithful not to be overly dismayed.
