What are the main figures of speech in ' The Blessed Damozel' by Dante Rossetti?

The main figure of speech is ekphrasis, which is extended description. The poem tends to employ many similes, i.e. explicit comparisons signalled by the term "like", and a fair amount of hyperbole, i.e. overstatement used to give a sense of superlative. The religious symbolism functions as a series of allusion. Some of the internal speeches can be considered forms of apostrophe, or direct address.
