THe Meridian is a circle beginning due South, and so passing by youre Zenith that is right ouer the crowne
of your head, and so by the two Poles of the worlde: and if you doe trauell due South and North, you doe not chaunge youre Meridian: but in the going or trauelling any other way, you do chaunge it.
THe vse of the Meridian circle is, to knowe the iust tyme of noone by the Sunne: for as soone as the middle of the Sunne is vpon the Meridian, then it is noone, and when the Sunne, Moone, or any Star is vpon the Meridian, then they be farthest from the Horizon, and it is a meete time to take their heigth for to know the altitude or heigth of the Pole of the worlde, whereby you may perfitly knowe howe farre you bee too the Southwardes or Northwardes of any place.
