How so, Nalion? Would you elaborate, please?

You're only describing one side of the equation, Lorkhan, the other is Akatosh. I think some worthy questions regarding "mantling" in this case would be:
"What persons/entities did they - Tiber/Talos/Zurin etc - mantle?"
"Which previous events did they refer to or which myths did they reenact." (Walk like them and do like them to become them - mythopoeia, reenaction/retelling of mythic events)
Because I don't have much time right now, I'd just like to briefly point to the following events:
- Pelinal, Alessia, Morihaus and the creation of the First Empire of Men
- King Hrol, the hill and his offspring Reman (not to forget the shepherdess Sed-Yenna) and the (re-)creation of the Empire (Second Empire of Men)
- Talos and Zurin and the creation of the Third Empire of Men
All these share mythic similarities, in my opinion. It goes even beyond that - Anu/Padomay, Lorkhan/Akatosh and the subsequent creations, especially the creation of Nirn.
The Song of Pelinal, the Trials of St. Alessia and the Remanada should serve as the most important sources.
