The excerpt is an example of invocation.

Explanation:

Invocation is a convention of classical literature and epic poems. At the beginning of the poem, or at the beginning of each canto, the author addresses a muse or deity, asking for help and inspiration to write. The word invocation comes from the Latin invocatio - to summon or to call upon. Invocations are considered a type of apostrophe, which is an address to a dead or absent person.

In the famous epic poem "Odyssey", by Homer, the invocation is as follows:

Tell me, Muse, of the man of many ways, who was driven

far journeys, after he had sacked Troy’s sacred citadel.

Many were they whose cities he saw, whose minds he learned of,

many the pains he suffered in his spirit on the wide sea,

struggling for his own life and the homecoming of his companions.
