Discover the wonders of the equinoxes through the lens of history and culture. The Peking Observatory, illustrated in Jean Baptiste du Halde's Divers voyages, marks the beginning of scientific exploration of this astronomical phenomenon. Spring tides near Honfleur, France, and the SEINE MASCARET (P. PARIS) bear witness to its impact on the tides. Tabula secundum accurata Ventorum veterem et nova, an ancient wind table from Asia, aids navigators in their equinoctial journeys. In India's Rajasthan, Jaipur's (Pink City) Samrat Yantra (giant sundial) and Horizontal Sundial with Wind Rose continue the tradition of astronomical innovation. Astronomical Quadrants Illustration C017 / 3536 and the Sundial further illustrate the importance of the equinoxes in timekeeping. Dantis Equinoctial Armillary, a complex astronomical instrument, offers a glimpse into the intricacies calculations. Amidst it all, a stormy night at the Jantar Mantar serves as a reminder of the enduring allure of the equinoxes.
