Meaning

Euthys means straight; its feminine form can stand for an understood straight line. The geometrical sense differs from the adverbial “immediately.”

Use in the book

The celestial description asks the reader to imagine a straight line joining the two fixed poles. This line is the axis and a diameter of the spherical cosmos, with earth at its center. Straightness specifies the imagined connection, whereas circular motion belongs to the revolving whole.
