There are two main sections in St Botolph's. The first 25 lines can be quite confusing especially with all the astrological terminology. We should not worry about the specific details of the astrological section of the poem but we can still ask ourselves, what is the general meaning of the first section of the poem do you think?
Both Hughes and Plath were interested in the occult and divination. Hughes believed like some other writers that writing was a spiritual activity that connected God or the divine to the earth. The divine communicates through the writer.
Speculating about Plath, I wonder whether Plath was interested in the occult as a way of reconnecting with her dead father.

Here is a note about Chaucer and Dante
Both medieval poets wrote about journeys in their poetry. Chaucer wrote of a group of pilgrims making a pilgrimage from London to Canterbury. Some of the stories told include the work of astrologers.
Dante's journey is recorded in the Divine Comedy in which Dante searches for his beloved Beatrice. His journey takes him through hell, purgatory and finally paradise.
Shakespeare refers to Romeo and Juliet as 'star crossed lovers'.
