The Colosseum Vault's door

The number 72 played a significant role to the modern-day Assassins. Most notably, it was used as the password to gain access to the Colosseum Vault during the retrieval of the Apple of Eden in October 2012.


As evident in the Scrolls of Romulus, the earliest-known user of the number 72 as the password to the Vault was Marcus Junius Brutus, circa 45 BCE. The next known person to open the Vault was Ezio Auditore da Firenze in 1506, to seal the Apple of Eden he possessed within. Due to Desmond Miles' vision of Ezio in the Sanctuary, it was known that Ezio later returned to the Villa Auditore to leave behind the clues to the password, which would allow future Assassins to access the Vault and obtain the Apple.

Ezio left the clue on the Sanctuary staircase, just behind the bookcase in Mario Auditore's study. It consisted of a tetractys, an etching of an equilateral triangle with nine other equilaterals within it – the same marking found on the Colosseum Vault's door – and the numbers 1419, 1420, and 1421, which were only visible to those who possessed the gift of Eagle Vision.

Modern-day discovery

"The Tetragrammaton. The 72 names of God. You see? They're all contained within three verses: Exodus 19 through 21. And, get this, you'll like this. If you arrange the four Hebrew letters in God's name within an equilateral triangle, their numerical values add up to the same number: 72."
―Shaun explaining the password to the other Assassins.[src]

Desmond and Lucy examining the markings

When the group of Assassins first arrived at Monteriggioni and gained access to the Sanctuary, Desmond noticed and read out the numbers written into the wall. Shaun Hastings posited them to indicate years, though he could not think of their significance to each other. After discovering the Apple's location through the use of the Animus, the Assassins pondered on how to access the Vault under the Colosseum. Rebecca Crane discovered that the door required a password, but a power failure cut short their attempts to discover it.

As the Assassins waited in the dark and contemplated their next move, Desmond remembered the markings and pointed them out. With this, Shaun finally discovered the numbers' significance and explained them to the rest of the team; pointing out the 72 names of God found in the Bible's book of Exodus, contained within chapter 14, verses of 19 to 21. Having obtained the password, the Assassins left the Sanctuary and headed for the Colosseum. As Desmond made his way through the ruins of the landmark and the path of the Lair of Romulus underneath, Lucy Stillman realized that the current date, October 10, was exactly 72 days away from the Abstergo Industries satellite launch on December 21.

Though she wondered aloud if it was more than a coincidence, Desmond dismissed her unease, stating that, "Someone probably wanted to make sure we get the password right." The team eventually arrived at the Temple of Juno, where the door to the Vault was located. After briefly wondering if the door would understand English, Desmond spoke "72" aloud, subsequently opening the Vault and allowing the Assassins to enter. As Desmond activated the Apple in the Vault, the Isu Juno told him that his journey would begin on the 72nd day before the awakening.
