Perhaps the most remembered writing of I look (in literary circles) is the Sigüenza Book, a continuing series of impressionist vignettes published beginning in 1907. In the style of this book I look shows his affiliation with the modernist movement of Rubén Darío. Sigüenza he is a Franciscan monk; he is meditative, withdrawn, a lover of defenseless animals.
