That's right, guys. The horse has been documented since the 14th century as a symbol of the ancient Saxons and their ruling house, the Welfen/Guelphs - the so-called Sachsenross/Saxon Steed. For at least 400 years it has also been found on the gables of Low German houses as a decorative element (the mouldings were intended to prevent the thatched roof from fraying).
The Nazis emphasised that it was an ancient Germanic symbol. To what extent is this historically tenable? At the very least, its use in prehistoric times is hardly provable.
In any case, the steed can still be found as a symbol today - for example of the post-war federal state of Niedersachsen/Lower Saxony or also in Twente's coat of arms.
