2 Their pleasaunt tunes they sweetly thus applide;
O thou faire sonne of gentle Faery,
4 +That+ art in mighty armes most magnifide
Aboue all knights, that euer battell tride,

Here may thy storme-bet vessell safely ride;
8 This is the Port of rest from troublous toyle,
The worlds sweet In, from paine and wearisome turmoyle.

4 That > Thou _1596_

arms > {Feats of arms}
magnified > lauded

7 Here may your storm-beaten vessel safely ride;
8 This is the port of rest from troublous toil,
9 The world's sweet inn, from pain and wearisome turmoil."

turmoil > harassing labour, toil
