Then sighing softly sore, and inly deepe,
2 She shut vp all her plaint in priuy griefe;
For her great courage would not let her weepe,
4 Till that old Glauce gan with sharpe repriefe,
Her to restraine, and giue her good reliefe,
6 Through hope of those, which Merlin had her told
Should of her name and nation be chiefe,
8 And fetch their being from the sacred mould
Of her immortall wombe, to be in heauen enrold.
