Checked Strasbourg grain prices around the 1518 dancing
Used Allen's copy of Hanauer's Strasbourg prices. Bread grain was very dear in 1516 and 1517 and back to normal in 1518. This confirms the dearth but corrects our timeline: the dancing came a year after the worst hunger. No price signal across the other dances.
