In the Alfonsine Tables, compiled in Spain in the 13th century, Deneb was listed as Denebadigege. As the Sun leaves the winter solstice and Sagittarius behind, it moves into its next zodiacal station, Capricornus, the "water goat, and in early February crosses between the figure's head and tail, between Algedi (Alpha Capricorni) and our star Deneb Algedi, the Delta star. This means that some parts of their stellar surface are contracting while others simultaneously expand. Visual magnitude: 1.25 The Chinese know Deneb as the Fourth Star of the Celestial Ford (天津四), referring to the Chinese asterism Celestial Ford (天津), formed by Deneb with Sadr (Gamma Cygni), Fawaris (Delta Cygni), 30 Cygni, Nu Cygni, Tau Cygni, Upsilon Cygni, Zeta Cygni and Aljanah (Epsilon Cygni). Polaris, the current North Star, is a much better indicator of true north, being located within 0.5° of the pole, but at magnitude 1.98, it is also considerably fainter than Deneb.
