Mental Floss presents an interesting assortment of emblems and symbols on national and territorial flags that tells the lore behind the scampering marten of Croatia, the Phrygian cap (hat on a stick) motif that represented manumission from slavery, and made me think of the aurochs, an extinct wild bull of Europe that’s on many coats-of-arms. I did not know, however, why Bermuda has, seemingly inauspiciously, a shipwreck on their flag and how that near-disaster inspired Shakespeare to pen to The Tempest—and nor did I realise that for its side bar of five intricately woven carpets representing the five chief tribes, the flag of Turkmenistan is considered the most vexillogically complex banner in the world.
