Here is a nice collection¬†of historical maps of time (“timelines” being too simple a term for these sinuous creations).

This reminds me of (and I think some of the same images are included in) the book Cartographies of Time.

Always something fascinating to me about the 2D representation, across a flat space, of something that is multilayered and complex; an impossible task, it would seem, and yet we routinely (if imperfectly) pull it off.
