the unseen stuff you will probably need next year but it does still apply to the pre-1900 anthology, it's just general poetry advice at the end of the day. Old poems are great because they tend to have a lot more devices as well as a strict metre. Go through each poem and look for those things. Try to find a (plausible) reason why they link to/help emphasise the type of love in the poem. E.g. caesura= partings, finality, futile love.
