Final answer:
The poetic device in 'She stands with aspect sad but high' is personification, attributing human characteristics to a non-human aspect.
Step-by-step explanation:
The poetic device found in the bolded words 'She stands with aspect sad but high' is personification. This figure of speech is used to give human characteristics to something non-human, or to represent an abstract quality in a human form. In this context, 'aspect' is being personified with the ability to be 'sad but high,' attributing human emotions and states to a non-human entity.
Poetic devices such as similes and metaphors involve comparisons between two things; a simile uses words 'like' or 'as' to compare, while a metaphor directly states the comparison. Hyperbole is an extreme exaggeration used for emphasis or effect. These devices are different from personification, which is the application of human traits to objects or concepts.
