From 'Orlando Furioso,' Canto 23
The course in pathless woods, which without rein
The Tartar's charger had pursued astray,
Made Roland for two days, with fruitless pain,
Follow him, without tidings of his way.
Orlando reached a rill of crystal vein,
On either bank of which a meadow lay;
Which, stained with native hues and rich, he sees,
