But, look, the morn, in russet mantle clad,
Walks o’er the dew of yon high eastward hill.

– William Shakespeare

Hamlet, Act 1, Scene 1. Horatio uses figurative language and vivid imagery to signal that it is daybreak and the sun is coming up. He uses the metaphor of “in russet mantle clad” to describe the dawn and its reddish-brown color. The morn is personified as having feet to walk over the dew of a high hill. The quote comes just after the exit of the Ghost, which has made another appearance on the castle battlements.
