Sin título, librettos

"Sin título, Librettos" consists of 42 notebooks which guises resemble musical score books. Though, they do not contain notation systems but numerical series. Altogether there are seven series of multiples of the first seven prime numbers (1, 2, 3, 5, 7, 11, 13). The multiple sequence of 2 is written down in two booklets, the sequence of 3 in three, the sequence of 5 in five booklets etc. Libretto Uno contains blank spaces which match the number of prime numbers belonging to that series. This work is an homage to the enigma of prime numbers and the research that has been done in that area by C. F. Gauß and B. Riemann.
