[1] His travels and association with avant-garde writers in France, Cuba, and New York compelled him to reinvigorate the Dominican poetic sensibility by rejecting formal models and rhyme, being the first poet to introduce free verse in Dominican letters with his poem, Arabesco (1917).

Diaz was born in Santo Domingo on April 6, 1880, the son of Francisco Vigil and Isabel Díaz.

[3] Greatly influenced by the French literature of that era, Diaz’s travels to Paris, New York, and Cuba in the early years of the twentieth century marked his literary production.

[4] Díaz's poems and essays were published in a multitude of journals, including Cromos, Letras, La Cuna de América, Renacimiento, Cosmopolita, Bahoruco, El día ético and Blanco y Negro.

[4] As the story goes, after the death of Jules Vedrines, the French aviator who had acquired fame on his Paris-Madrid flight for having created the dangerous aerial pirouettes of 'looping the loop', Vigil Díaz, pursuing more experimental forms and the total liberation of the verse named his new sensibility vedrinismo; In this sense, his verses were verbal pirouettes, referring to the phonic game he was looking for in his writings.
