Final answer:
Homer is believed by some to have been blind based on the portrayal of blind poets in ancient Greek literature and the earliest statues of him showing vacant eyes.
Step-by-step explanation:
Homer is believed by some to have been blind due to several factors. First, blind poets were a common character in ancient Greek literature, so it is possible that Homer, as a poet, could have been blind as well. Second, the earliest statues of Homer depict him with vacant eyes, which could be interpreted as an indication of blindness. However, it is important to note that there is debate among historians regarding the historical existence of Homer and whether he was a real person or a legendary figure.
