1. Symbolism is the idea that things represent other things.

The use of objects to express or represent ideas or qualities - Symbolism;
2. Allusion is a figure of speech, in which an object or circumstance from unrelated context is referred to covertly or indirectly.
A reference to a well-known text, person, or event - Allusion;
3. Imagery is a literary device used in poetry, novels, and other writing that uses vivid description that appeals to a readers' senses to create an image or idea in their head. Through language, imagery does not only paint a picture, but aims to portray the sensational and emotional experience within text.
Vivid language that appeals to sight, sound, touch, taste, or smell - Imagery.
