Three poems were written by Theodoros Prodromos in connection with Isaakios, the brother of Ioannes II. One, in Isaakios' own persona, was specially proud of his pilgrimage to Jerusalem and his investment in bringing water to the monastery of Hagios Ioannes Prodromos at the Jordan. A second, from its title, was written to accompany the gift of a picture to Ioannes II, a portrait of Ioannes himself painted by Isaakios (though the poem itself throws doubt on this scenario). It speaks of their closeness of upbringing and the trivial quarrel which had divided them. A third, a hexameter encomium, stressed his double imperial descent, his excellent education and his warlike skills; though it has no dating criteria, it may well have been written, like the other two, to celebrate Isaakios' return to Byzantium
