Romanos started negotiations to marry his infant son to one of Robert Guiscard's daughters

Summary:
Romanos IV proposed to Robert Guiscard a marriage between his infant son (Nikephoros) and one of Guiscard's daughters. Romanos was later presented by Michael VII as a usurper, who had been removed by God - so Michael's later proposal, outlined in letters written by Psellos, was much sounder
