<human>:  I have a question about the enny-poems of William Shakespeare. Who is the narrator of Sonnet 73?
<bot>: The narrator of Sonnet 73 is the poet himself. The poem is a sonnet, which is a form of poetry that has a fixed number of lines and a rhyme scheme. The first line of the poem is "That time of year thou mayst in me behold", which is a reference to the season of spring.
