(because of how Tumblr keeps showing me both 1. stuff about the new Superman movie and 2. ads for Tumblr Premium)
that Superman’s S symbol is within the shape of a diamond.
Not a diamond as it grows in nature, on any planet where carbon exists and has the conditions to crystallize in that form
(octahedral D-8 shape, reason why we call that type of quadrilateral a “diamond shape”)
but like. the side view of a cut diamond. in the typical way it is usually cut by jewelers. in present day, on the planet earth.
flat top. girdle. the whole thing.
i know canon superman comics have some after-the-fact rationale about what the S means in Kryptonian… but do they have anything about why the diamond shape? …or is it just part of the rationale for the symbol as a whole
