The speaker is envisioning crowded streets. He sees the happiness the people around him are enjoying by saying that life is in endless overflow. Not only is he descrbing the happiness around him but he is also describing the pain he sees around him. You can tell by the words he uses such as "Thunder of thoroughfares; trumpets that blow."
He goes on to say that sailors have anchored their fleets meaning that they just came home. He describes the sounds of bells tolling and the voices of children. Bright flowers are also describes as a positive thing in this poem as almost an incentive to be happy. This can be seen almost as a perfect disaster with the dark undertones and then you have the positive that almost outways all the bad the speaker has endured.
The speaker talks about having visions of poets that are better than him. He goes on to talk about greek mythology with the reference the Muses saying that they loved this poet who he claims is superior to him. He says they laid a lyre of gold in his hands and crowned him with a laurel crown and placed him as the God of music on the throne. Basically calling him their leader and that he is nowhere near that he sees himself as inferior to who or what he is refering to.
In the first stanza the reader is hit with a strong visual with crowded city streets. He focuses a lot on the people around him and how they are acting. You can tell because of his wording saying things such as crowded city streets and human life in endless overflow. After that you also get a portion of the poem that is auditory. He talks about the Thunder of the roads and the trumpets. This is also an Alliteration with the repatiton of the letter T and B. The visual and auditory part of this poem seems to almost contradict one another with the almost peaceful scenery and the dark and negative noises.
In the second stanza the poet gives you even more auditory things and a visual. The auditory is the biggest here with the clamor, the tolling of the bells, and the childrens voices. This part of the poem gives you a positive vibe like everyone is happy. Then with the visual you learn that he says to battle and obscure retreats and the bright flowers. It almost seems as if it is a perfect disaster because you have this negative part of it referring to a war it seems but then you have these visuals that give of an auora of everything being perfect.
In the third stanza you are hit with even more visuals when he goes and talks about garden-walls and intermingled sweets. He continues on talking about a vision that he has or constantly has when he unfolds or rests. This could be him doubting himself and his abillities therefore he has trouble relaxing he doesn't think he is good enough. This is evident when he is talking about the Poet paramount which means more important than anything else.
In the fourth stanza he uses a lot of different things such as visuals, greek mythology, and even some tactile in this portion. He describes the Muses which refers to the nine muses and saying that who or what ever is limiting him that the muses love every single one of them do. He also describes them placing a lyre of gold in is hands which is a stringed U-shaped instrument. Not only that but also this thing or person is crowned with a laurel crown and placed on a throne like Musagetes that is also known as the Greek God Apollo who is the God of music. This last stanza is filled with refrences to Greek Mythology.
