Pessoa created this heteronym as "Master" of the other heteronyms and even Pessoa himself. Georges Zuk, a purported French surrealist poet, was a heteronym created by Skelton. Pessoa's earliest heteronym, at the age of six, was Chevalier de Pas. The book was originally signed as a heteronym work. He wrote some of his work under the heteronym Marek van der Jagt. Heteronym pronunciation may vary in vowel realisation, in stress pattern, or in other ways.
