5 saw > saw, 1590, 1596
1 At last, when, drunk with drowsiness, he woke
drunk > [unsteady, intoxicated; or, perhaps: satiated]
2 And saw his drover drive along the stream,
drover > {Boat used for fishing with a drift-net} stream > current
3 He was dismayed, and thrice his breast he struck, 4 For marvel of that accident extreme;
accident > occurrence, happening
5 But when he saw that blazing beauty's beam, 6 Which with rare light his boat did beautify, 7 He marvelled more, and thought he yet did dream, 8 Not well awaked, or that some ecstasy
awaked > awoken, aroused; awake ecstasy > rapture
9 Assotted had his sense, or dazed was his eye.
