An 8[degrees] field includes the Moon, Venus, Mars, the star Alnath
(Beta Tauri), and the open star cluster NGC 1746, which shows beautifully in binoculars and small telescopes.
And by his eighte speere in his wirkyng And by the eighth sphere in its working He knew ful wel how fer Alnath was shove He knew full well how far Alnath was shoved Fro the heed of thilke fixe Aries above, From the head of that fixed Aries above, That in the ninthe speere considered is; That in the ninth sphere considered is; Ful subtilly he kalkuled al this.
Finding the Sun's position required a similar use of arguments and equations, with an additional complication alluded to by Chaucer's mention of "Alnath," a medieval name employed both for the single star Alpha Arietis and also for the stars in Aries that formed the first lunar "mansion." The 28 mansions were groups of stars near the ecliptic used as reference stations for the daily motion of the Moon during the sidereal month.
El Nath, or Alnath
, helps complete the pentagon of Auriga but is really Beta Tauri, for it marks the more northerly of the Bull's horn tips.
On April 22nd the waxing lunar crescent is below Venus, and then on the 23rd it is upper left of Venus and right between Mars and similarly bright Alnath
. The fattening Moon shines to the right of Saturn on April 24th and near Jupiter again on the night of April 29-30.
Their positions are shown on the map for February 28 when Ceres lies exactly on a line between Alnath
and Tau Tauri.
