Because an autobiography is using events from a persons life which, with other peoples conformation, are facts.
I'm pretty sure it's B- painful
I would say that the lines which show us how desperate the poet is are the following:
"... helpless in my throes, Biting my truant pen, beating myself for spite--"
As you can see here, the poet says he is helpless, meaning that he cannot find inspiration to write what he wants to write. Therefore he is desperate for some inspiration, which is why he is biting his truant pen in order to show how anxious he is to get his inspiration back.
Is there any picture or an article to this ?
Mark Antony, the famous Roman Senator and one of the Triumvirs during the Second Triumvirate, the time of transition of Rome from Republic to Empire, was best know for two things; the first, having been the lover of Cleopatra, Queen of Egypt, after his best friend, Julius Caesar, and the second, for his deep friendship with Caesar himself. From 54 B.C, when Antony was elected as tribune, he dedicated himself to defending Julius Caesar in front of the Senate and became his greatest supporter. In fact, while Julius Ceasar was a dictator in Rome, Antony supported him and in 48 B.C, Antony became part of the Caesarean forces in the Battle of Pharsalus and also made part of the famous Republican Civil War. In 44 B.C, when Caesar assumed his fifth term as consul, Antony became co-consul. After the death of Caesar, Antony had to flee Rome dressed as a slave but came back soon after and took over responsibility over Caesar´s will. But what shows how deeply Antony respected and admired Julius Caesar was B, when Antony gives a speech to the people underlining the greatness of their fallen leader Julius Caesar.
