What is the author's style in For an Assyrian Frieze by Peter Viereck?

The poem can be broken into three parts. The first part is a description of the frieze and how it begins to speak to the narrator; the second part is what the lion has to say; and the third part is the narrator's interpretation and understanding of the importance of the lion's words. This tripartite division of content is mirrored in the three-line structure of the verses. Dante, also, used a tripartite structure in his lines and content, but for Dante that structure was also the structuring principle of the poem as a whole, after all, the tripartite structure was inspired by the Holy Trinity, which is the real subject of Dante's poem.
