Theōnos Sophiston Progymnasmata = Theonis Sophistae Primae apud rhetorem exercitationes
This Greek and Latin edition of Theon's rhetorical exercises was published in Basel in 1541 by Johannes Oporinus, with commentary by Joachim Camerarius, for students of classical rhetoric. Its pictures are small woodcut historiated initials, each letter enclosing a figure, creature or foliage, offering a designer a compact set of decorative capital letter frames with Renaissance character.
