Now, prosp'rous gales the bending canvas swell'd;
From these rude shores our fearless course we held:
Beneath the glist'ning wave the god of day
Had now five times           the parting ray,
When o'er the prow a sudden darkness spread,
And, slowly floating o'er the mast's tall head
A black cloud hover'd: nor appear'd from far
The moon's pale glimpse, nor faintly twinkling star;
So deep a gloom the low'ring vapour cast,
Transfix'd with awe the bravest stood aghast.
