Celestial navigation Celestial navigation Celestial navigation, also known as astronavigation, is the ancient and modern practice of position fixing that enables a navigator to transition through a space without having to rely on estimated calculations, or dead reckoning, to know their position. Celestial navigation uses "sights", or angular measurements taken between a celestial body (e.g. the Sun, the Moon, a planet, or a star) and the visible horizon. The Sun is most commonly used, but navigators can also use the Moon, a planet, Polaris, or one of 57 other navigational stars whose coordinates are tabulated in the nautical almanac and air almanacs.
Zisa (goddess) Zisa (goddess) Zisa or Cisa is a goddess in Germanic paganism. "Zisa" is an etymological double of Tyr or Ziu according to 19th century scholar Jacob Grimm who suggests that Zisa may be the same figure as Tyr's unnamed wife, mentioned by Loki in the 13th century Poetic Edda poem "Lokasenna". Zisa is mentioned in manuscripts from the 12th to 14th centuries which reference a victory against the Roman Empire attributed to the goddess. The anniversary of this victory was celebrated on the festival day of September 28 and involved games and merrymaking. Scholar Stephan Grundy, and authors Nigel Pennick
