Nicholas Kallikles’ poem 29 Εἰς τὰ ῥόδα is a rich and fascinating text which resists its classification as religious epigram and rather inscribes itself in the tradition of spring ekphrasis, of which it constitutes a good twelfth-century example. The relevance given to themes such as learning and rhetorical ability, whose importance is strongly stressed, and the analogies that the text shows with poems related to school contests suggest that it was probably intended to be performed as the opening of a school competition taking place in the theatron. The existence, in mss. Vatican City, Biblioteca Apostolica Vaticana, Pal. gr. 92 and Florence, Biblioteca Medicea Laurenziana, conv. soppr. 2, of a schedos on spring attributed to Kallikles and showing some points of contacts with poem 29 supports this hypothesis and suggests that Kallikles, known mainly for his medical teaching, might have engaged for some time also in the teaching of grammar and rhetoric.
