The fall equinox is celebrated in many different ways by practitioners of Ásatrú and Heathenry. Those who practice modern forms of polytheistic religions rooted in Northern Europe have revived, reconstructed, and reimagined a variety of practices and rituals to mark the turning of the year from summer to autumn. Haustblót (autumn sacrifice) is mentioned by name in the saga of the Icelandic warrior-poet Egill Skallagrímsson. The Ynglinga Saga of Snorri Sturluson tells of laws established by the god Odin, including the timing of the main annual sacrifices:
Þá skyldi blóta í móti vetri til árs, en at miðjum vetri blóta til gróðrar, hit þriðja at sumri, þat var sigrblót. There should be sacrifice toward winter for a good year, and in the middle of winter sacrifice for a good crop, a third in summer, that was victory sacrifice.
