OTTAZIANO, PORFIRIO. - When the Emperor Costantino celebrated his vicennalia in 325, he received as a gift from an exile, Publius Optatianus Porfirius, a member of high society, a collection of 20 panegyric poems. The gift had the desired effect, and P. was recalled from exile.
These poems were subsequently published by their author together with others and with the Emperor’s letter of thanks. They are carmina figurata, already known in Alexandrian art, which represented, through the arrangement of the individual letters, objects, squares, diagonals, etc. Christian elements are found in O. alongside others of ancient origin. Poems of this kind
enthused Ennodio in his youth and are also found in the work of Venanzio Fortunato, Bonifazio Alcuino, Rabano Mauro, etc.; they are likewise known in Persian art.
