Sirius and Wep Ronpet
The Opening of the Year — the cosmic New Year of the ancient Egyptians
Wep Ronpet — "the Opening of the Year" in ancient Egyptian — marked the most sacred day of the Egyptian calendar. This day corresponded to the heliacal rising of Sirius, when the star reappeared at dawn after 70 days of invisibility.
The heliacal rising of Sirius is not just an astronomical phenomenon. It is a millennial meeting between humanity and the cosmos, a moment where science and spirituality meet in the light of dawn.
In Guadeloupe, observing this phenomenon connects us directly to African roots, where Sirius was venerated as the herald of life and renewal.
