The paper establishes an analogy with the literature of Spanish writers Fray Luis de León and Miguel de Cervantes (through the alternate distribution of ferrite/cementite lamella e), as well as with the painters Maurits Cornelis Escher and Victor Vasarely (through the multi-level organization of their paintings) and the composer Johann Sebastian Bach (through the hierarchical structure of his music). © 2020 The Authors.
