He taunts Cervantes with being old, with having lost his hand, with having been in prison, with being poor, with being friendless, accuses him of envy of Lope's success, of petulance and querulousness, and so on; and it was in this that the sting lay.

Avellaneda's reason for this personal attack is obvious enough.

Whoever he may have been, it is clear that he was one of the dramatists of Lope's school, for he has the impudence to charge Cervantes with attacking him as well as Lope in his criticism on the drama.

His identification has exercised the best critics and baffled all the ingenuity and research that has been brought to bear on it.

Navarrete and Ticknor both incline to the belief that Cervantes knew who he was; but I must say I think the anger he shows suggests an invisible assailant; it is like the irritation of a man stung by a mosquito in the dark.
