Person or legend …

… Who was Homer? – The British Museum Blog. (Hat tip, Dave Lull.)

Everyone is entitled to their own view on this. My own is that it is not inconceivable that there was an original bard who came from the part of the world that we now know formed the setting of the poems. Perhaps he composed the epics in outline, building on stories passed down from his parents, grandparents and great-grandparents, which later poets developed and perpetuated orally. Finally these poems were written down.
