For those like me who didn't know the reference, see [1] Aaron Schuster, "Bachelors, Snakes, and Squiggles: The brief history of a famous literary doodle" (2009). Not only is the squiggle part of [2] _Tristram Shandy_ (1759), it — the squiggle — was also quoted by Balzac as the epigraph to [3] his novel _The Wild Ass's Skin_ (1832). Wikipedia [4] says: "Balzac never explained his purpose behind the use of the symbol, and its significance to _La Peau de chagrin_ is the subject of debate."<p>[1] <a href="https://www.cabinetmagazine.org/issues/36/schuster.php" rel="nofollow">https://www.cabinetmagazine.org/issues/36/schuster.php</a><p>[2] <a href="https://archive.org/details/lifeopinionsoft00ster/page/554/" rel="nofollow">https://archive.org/details/lifeopinionsoft00ster/page/554/</a><p>[3] <a href="https://archive.org/details/tudesphilosoph01balz/page/n12" rel="nofollow">https://archive.org/details/tudesphilosoph01balz/page/n12</a><p>[4] <a href="https://en.wikipedia.org/wiki/La_Peau_de_chagrin" rel="nofollow">https://en.wikipedia.org/wiki/La_Peau_de_chagrin</a>
