The drawings he made on this relatively short journey confirm
that Rivera went in search of public and monumental art, in other
words, the art in churches and decorated civil buildings that was
directed toward the masses. He particularly observed the mosaics
at
San Apollinare Nuovo
in Ravenna, frescos and countless religious
paintings.
