...well, the first few terzine. Not that I intentionally learned it, but it's the kind of poetry that some gets stuck in your brain. You simply cannot forget it (and this is only true for the Italian, all translations are only a faint echo of the original).

Великолепен стихотворный голод итальянских стариков, их зверский юношеский аппетит к гармонии, их чувственное возделение к рифме -- il disio!
(О. Э. Мандельштам, Разговор о Данте)
