English to Italian Art/Literary Music

Hello,
My name is Antonio and I'm an Italian student. I'm so sorry to bother you, but I have to find this answer and I don't know anywhere else to ask it but this forum, due to the fact that somewhere else someone closed my topic and I didn't get what I wanted to know. So I appreciate any kind of help and I hope no one will close my topic again. Well, in this period of my life, I'm hucked on a song, "The One" by Kylie Minogue. And she sings:
"It's a feeling that I need to know, Close to touch like Michelangelo". I know what it means and I also translated it and I brought it to my teacher to read my translation and make some adjustments. And when she heard "close to touch like Michelangelo", she said that it was taken from an American poem, but she couldn't remember who was the author or what was the name of the poem. And she said that due to the fact that the sentence was culturally bound, I had to find the official translation of the original text and I had to use it in my translation, according to copyright, etc. So could someone tell me if it's taken from a poem or it's Kylie's own creation. And if it's taken from a poem, could someone tell me who is the author and the name of the poem. Thank you so much!!!
