The more common report is that Remus mockingly jumped over the newly raised walls and was forthwith killed by the enraged Romulus, who exclaimed, "So shall it be henceforth with every one who leaps over my walls."
Vulgatior fama est ludibrio fratris Remum novos transiluisse muros; inde ab irato Romulo, cum verbis quoque increpitans adiecisset 'sic deinde, quicumque alius transiliet moenia mea', interfectum.
