world

An eighteen-thirty-two guidebook, highlighted by Boing Boing, laid out specific rules for travel through India. Merchants transporting diamonds across the Deccan Plateau were guided to depart on Tuesdays or Thursdays, targeting the fifth, thirteenth, or twenty-eighth day of the lunar month. The practices extended to diet: coriander seeds were eaten before Tuesday departures, and jaggery before Thursday ones. The book captures a moment when commerce and tradition intersected in the precision of travel planning.
