Eye

An Eye was a large round device constructed by the Isu Minerva to make calculations of existence and time. Using the device, she was able to generate possible outcomes of future events, and reach out to individuals across time to guide them in her desired direction. One part of an Eye was discovered by humans and became known as the Antikythera mechanism.

While working with Juno and Jupiter to create solutions for the impeding Toba catastrophe of 75000 BCE, Minerva used the first Eye to focus her attention on preventing a second disaster from destroying the world in 2012. With the Eye, she pinpointed Desmond Miles as the most individual who would most likely be capable of preventing the disaster.

Knowing he would relive the life of his ancestor Ezio Auditore da Firenze through an Animus, she used the Eye to appear before Ezio in the Vatican Vault on 28 December 1499 with a message for his descendant, warning him of the impeding solar flare. Eventually, Juno began to tamper with the device, prompting Minerva and Jupiter to destroy it and imprison Juno inside the Grand Temple.

After Juno was imprisoned, Minerva created a second Eye to reach out to Desmond once more on 21 December 2012, to determine whether he found a solution to prevent a second disaster. She discovered that Juno, whose consciousness had been digitally stored inside the temple, had been manipulating Desmond. Minerva urged Desmond not to use the global aurora borealis device, which would save the world from the solar flare but also free Juno from imprisonment, claiming that the world's destruction was better than Juno's release. In the end, Desmond decided to save the world, ignoring Minerva's warning.

In 2013, after researching the Eyes, Abstergo Industries discovered that the device would have been extremely difficult to use due to the nature of the calculations, and would have required hundreds of thousands of trials to calculate events so far in the future.
