dies iræ, dies illa (12. 052)

Fêted on this day in the Roman and Eastern Orthodox calendar of saints, Zephaniah (Σοφονίας, צְפַנְיָה, Concealed is god) was a priest of the Temple of Solomon during the reign of Josiah (circa 640 to 609 BC) counted among the Twelve Minor Prophets and credited as forecasting the coming of the Messiah, during a time when worship of other deities was popular and widespread, especially that of Baal and Astarte. The incipit of his book that warns of corruption and the imminent destruction of Jerusalem for its moral degeneration for its religious waywardness is the origin of the setting for the liturgical hymn as the sequence from the Requiem Mass—translated in the Vulgate edition of the Bible, “Day of wrath and doom impending!”
