And that mythical power still has a hold on us, as well.

而且这种神话般的力量仍然对我们有影响。

It was widely feared that Caesar would name Caesarion as his heir and that Cleopatra would then have a hold on the Roman Empire through her son.

人们普遍担心凯撒会任命凯撒里奥为他的继承人，克利奥帕特拉会通过她的儿子控制罗马帝国。

这里的想法是， 悲剧只出现在六世纪末， 也就是神话语言不再对城市的政治现实产生影响的那一刻。
