Question

how is death personified in the line nor shall death brag thou wonderst in his shade​

Answer 1

In this line , " Death " is being used primarily as personification . Personification is the granting of human thoughts and feelings to non-human things or ideas . Here , death is given the ability to " brag " and to " wander " and to provide shade . Obviously , the actual state of death can do none of these things .
