The morning of All Saints' Day, 1512
On the morning of 1 November 1512, Michelangelo's completed vault was uncovered as Pope Julius II entered the Sistine Chapel to celebrate Mass.
Julius formally inaugurated the chapel with its new ceiling at a Solemn High Mass that day. Giorgio Vasari recorded that the vault was uncovered on All Saints' morning as the pope came in to say Mass.
31 October was the deadline, not the reveal
Michelangelo had completed the second half of the vault by 31 October, which is what made the chapel available for the next morning's liturgy.
What the finished work replaced was the chapel's earlier painted starlit ceiling. Nine Genesis scenes now ran down the centre of the vault.
Not an exhibition, and not yet "il divino"
"Exhibited to the public" is less secure than "unveiled during papal Mass." The institutional sources establish a solemn liturgical inauguration but do not document a modern-style opening to unrestricted crowds.
Vasari records satisfaction and rejoicing rather than the amazed, speechless throngs of later retellings.
The accolade "il divino" was not attached to this unveiling either. Its first securely identified literary application is Ariosto's Orlando Furioso, published in 1516.

What the sources leave uncertain
- The date and liturgical inauguration are well supported by Vatican records and Vasari's account.
- “Exhibited to the public” is less secure than “unveiled during papal Mass.” The institutional sources establish a solemn liturgical inauguration but do not document a modern-style public opening to unrestricted crowds.
