when ptolemy xiii realized that his sister was in the palace consorting directly with caesar instead of at pelousion, he attempted to rouse the populace of alexandria into a riot. caesar arrested him then used his oratorical skills to calm the frenzied crowd gathered outside the palace. caesar then brought cleopatra vii and ptolemy xiii before the assembly of alexandria. here he revealed the written will of ptolemy xii—previously possessed by pompey—naming cleopatra and ptolemy xiii as his joint heirs. caesar then attempted to arrange for the other two siblings, arsinoe iv and ptolemy xiv, to rule together over cyprus, thus removing potential rival claimants to the egyptian throne. this would also appease the ptolemaic subjects still bitter over the loss of cyprus to the romans in 58 bc.
