MK said he had been represented as a minotaur by artists trying to convey the "man and bull at the same time" without going all Picasso. It doesn't matter what he actually were, anyway. It's all representations created by mortal mental stress.
The metaphysics are caused by myth, because TES is nothing more than a story created in a single but fragmented consciousness. The Mad Godhead thought of the same events in different ways, and can't tell which "really happened" because none of them really happened. So, loss of linear time, and dragon break.
Time is nothing more than the illusion of sequentiality in the fabricated memories of the Mad Godhead.
Time is the physical (as in appearing as a Force, not within the physical Boundries of Space) emodiment of
AE (the eventual posibility), Space is the eventual response to AE, forming from
O, the illusion is sequencality to mortals, when they can't realise the loss of linearity during a period of chaos, as when the GodHead becomes whole (the fusing of Space and Time, Lorkhan and Akatosh, when the Dragon Breaks, and the First Mortal Wakes again).
Metaphysics aren't merely myth, they are what define the limitations of the Godhead. They exist before even Anu and Padomay exist, and well after into the infinite, they are the laws of existence; even Vehk knows this is truth (though these laws may be leapt over, in the case of Kalpa jumping, but AE corrects this, as seen in the case with Dagon).
AE is law; everything will eventually happen. Time is born of this, in response to Space dynamically being created paralel.
O is law; everything will eventually be. Space is born of this, in response to Time dynamically being created paralel.
These are not illusions, these are Metaphysical fact, the GodHead is merely a description of the sentient One and All that is governed by these rules and interprets them to mortal perspective, those who become One with the GodHead then can also interpret these laws, but they cannot be undone (if you were to try and undo space, time would also colapse, and everything would Zero Sum and
O would be acheived, which AE would eventualy split, and recreate the universe, for it is an infinite law of existence).
