a quinque per arcus.' These five arcs, or circles, are the five
parallel circles by which astronomers distinguish the heavens,
namely, the two polar circles, the two tropics, and the
equinoctial. The latter runs exactly in the middle, between the
other two circles, so that the expression must be understood to
mean, 'pursue not your way directly through that circle which is
the middlemost of the five, but observe the track that cuts it

[Footnote 16: _Haemus._--Ver. 219. This, which is now called the
Balkan range, was a lofty chain of mountains running through
Thrace. Orpheus, the son of Oeagrus and Calliope, was there torn in
