Ancient philosophers used poetry to express ideas, but also as mnemonic exercises for themselves and their students. The Pythagorean Golden Verses and Cleanthes’ Hymn to Zeus are good examples. Coming from oral cultures when writing down things was not so common, I suppose it came natural to them to versify their knowledge.
I have tried to arrange the most basic Stoic ideas and quotes into verses for my own use, as a memory exercise for a beginner. The result is a poem of ten tercets, using rhyme to make them easier to remember and “ready to hand”.
I know the result is by no means aesthetic, and rhyme sounds old-fashioned, but it is useful when memorizing, and it wanted to make it sound old style.
