Analysis of A Hamadryad Dies. Sonnet

Low mourned the Oread round the Arcadian hills;
The Naiad murmured and the Dryad moaned;
The meadow-maiden left her daffodils
To join the Hamadryades who groaned
Over a sister newly fallen dead.
That Life might perish out of Arcady
From immemorial times was never said;
Yet here one lay dead by her dead oak-tree.
"Who made our Hamadryad cold and mute?"
The others cried in sorrow and in wonder.
"I," answered Death, close by in ashen suit;
"Yet fear not me for this, nor start asunder;
Arcadian life shall keep its ancient zest
Though I be here. My name? - is it not Rest?"
