The miracle of the liquefaction of the blood of St Januarius happened again at the Cathedral of Naples, Italy, on September 19, the saint's feast day.
St Januarius was a Bishop of Naples who is believed to have been martyred around the year 305 during the Diocletian persecution.
His blood is kept in a sealed glass ampoule and traditionally liquefies three times a year: on September 19, December 16 and the Saturday before the first Sunday of May.
The blood of St Januarius liquefied in the presence of Pope Francis in March last year, the first time it had happened in the presence of a Pontiff since 1848 on Saturday.
