 Theodore Prodromos (c. 1100–c. 1170) continued the tradition of writing extensive commentaries on Aristotle’s works by authoring a still unedited commentary on the second book of Aristotle’s Posterior Analytics, heavily influenced by Eustratios’. A couple of his minor works are also worth mentioning. His Xenedemus is a short Plato-style elenctic dialogue on themes from Porphyry’s Isagoge. He also wrote a small essay, On ‘Great’ and ‘Small’, which contains a series of arguments against Aristotle’s doctrine in the sixth chapter of the Categories that ‘great’ and ‘small’ are not quantities but relatives, and not contraries.
