Robert Greene was one of these people, much of the irritability and excitable temper often found in the subordinate ranks of the poetical fraternity, and he often talks of himself, his doings and associates in a highly-colored and extravagant way.

But his reference to me is especially deliberate, being in the form of a solemn and last appeal to his friends among the scholarly dramatists to relinquish their connection with the presumptuous and ungrateful stage.
Can you change the hard English words to easy ones and make the long sentences a little bit short for me?
