The collection of Paola Meroni can be considered as a poem of the soul because, when it is believed to have understood it to the full, it is realized that its value escapes, is beyond the literal meaning of a word, a reference, of a hint.

Therefore, the "hidden" adjective of the title is interpreted in a broader sense: the verses are "hidden" not only because they speak of a secluded life, but also because they hide a treasure of thoughtful wisdom that does not ignore the pain but accepts it as a component of our dwelling for a given period on earth.
