If someone wants to begin with Baudelaire, I would recommend his collection Le Spleen de Paris[0] - it's not poetry in its usual sense, but a collection of prose poems. I still remember picking the book randomly at our city library when I was 15 and reading the very first poem, L’ Étranger:
THE STRANGER
"Tell me, whom do you love the most, you enigmatic man? your father, your mother, your sister, or your brother?"
"I have neither father, nor mother, nor sister, nor brother."
"Your friends?"
"There you use a word whose meaning until now has remained to me unknown."
"Your fatherland?"
"I am unaware in what latitude it lies."
"Beauty?"
"I would willingly love her, goddess and immortal."
"Gold?"
"I hate it as you hate God."
"So! Then what do you love, you extraordinary stranger?"
"I love clouds... drifting clouds... there... over there... marvelous clouds!"
The book has been with me ever since, and as I'm getting older and re-read it I always discover new things. After all, there are themes a person has to grow into.
