Every ninety years, twelve gods incarnate as humans. They are loved. They are hated. In two years, they are dead. This process has happened for thousands of years and is known as the Recurrence. The interval between Recurrences is known as the saeculum.
Ananke was present at the first cycle. The gods fought the forces of darkness and lost.
Though nothing is known about these Recurrences, according to the rule of a Recurrence every ninety years, working forwards from the 450s they must have taken place in roughly the 540s, 630s, 720s, 810s, 900s, 990s, 1080s, 1170s, 1260s, 1350s, 1440s and 1530s. However, working backwards from the 1650s, they would have taken place in the 1560s, 1470s, 1380s, 1290s, 1200s, 1110s, 1020s, 930s, 840s, 750s, 660s and 570s. Though this does not quite add up, it does not take into account the length of each individual Recurrence, each of which presumably lasted several years.
David Blake claimed that this Recurrence took place in the 1640s, and described it as a "vintage Pantheon". However, mathematically speaking, it could have taken place in the 1650s, depending on the exact dates of the 18th century Recurrence.
Nothing is known about the this Recurrence, which probably took place in the late 1730s or early 1740s.
The 2010s Recurrence began in 2013, and will end sometime in 2016. In this Recurrence, the Pantheon were incarnated as pop stars.
