The Wikipedia article on Homer pretty drat awful...
This comment thread  illustrates why this page  is really a mess, from a historian's viewpoint. Taking everything with a grain of salt, but it seems that wikipedia has some policies that do not agree with what is commonly viewed as good academic practice. The particular article on Homer gets ~ 100k views a week, so this is a problem.

Will the social sciences ever become hard science? (very likely no, and with good reason.)

The poetry that moves men to tears The comments of this article are full of thoughtful, insightful poems.
Anthony Holden's new anthology celebrates the poems that move men – with revealing contributions from the likes of Ian McEwan, Jonathan Franz...

From the comments section (which is just as fascinating as the article itself):
Those Winter Sundays by Robert Hayden

Those Winter Sundays

Sundays too my father got up earlyand put his clothes on in the blueblack cold,then with cracked hands that achedfrom labor in the weekday weather madebanked fires blaze. No one ever thanked him.

I`d wake and hear the cold splintering, breaking.When the rooms were warm, he`d call,and slowly I would rise and dress,fearing the chronic angers of that house,

Speaking indifferently to him,who had driven out the coldand polished my good shoes as well.What did I know, what did I knowof love`s austere and lonely offices?

Tilt and rotation of the planets.
