Answer:
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 <em>invocatio</em> - 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:
<em>Tell me, Muse, of the man of many ways, who was driven
</em>
<em>far journeys, after he had sacked Troy’s sacred citadel.
</em>
<em>Many were they whose cities he saw, whose minds he learned of,
</em>
<em>many the pains he suffered in his spirit on the wide sea,
</em>
<em>struggling for his own life and the homecoming of his companions.</em>
