I'm trying to understand the timeline of the celebration of Rumarie among Vulcans in relation to the the rejection of emotion to follow logic and Surak's other teaching.
It's hard to imagine Surak, his followers, and later somberly logic Vulcans taking off their clothes, greasing themselves up with Rillan grease, and chasing each other around. These weren't exactly primitive times on Vulcan either - they already had nuclear weapons and interstellar travel.
However, on the Voyager episode Meld, Tuvoc told Neelix this holiday was celebrated as such until 1,000 years ago. My research on Wikipedia and Alpha Memory seems to indicate that Surak lived 1,800 - 2,000 years prior, thus Surak and Vulcans for 1,000 years after his teaching still observed the customs of Rumarie?
If so, perhaps an explaination of the logic is in order.
Rumarie was an ancient pagan festival on the planet Vulcan that was last observed during the 14th century AD.
In 2372, while learning about Vulcan holidays, Neelix discovered Rumarie, which he described as a festival "full of barely clothed Vulcan men and women, covered in slippery Rillan grease, chasing one another." (VOY: "Meld")
