og上的题，不懂句子意思

tonect

The Emperor Augustus, it appears, commissioned an idealized sculpture portrait, the features of which are so unrealistic as to constitute what one scholar calls an "artificial face."

请问这句话的意思是什么啊？

主干又是什么？我感觉这像是两句话呢，the features前面是一句，后面是一句

请教一下会的人啦，谢谢

tonect

看到的会的人帮帮忙啦，不是很清楚的也可以发表一下意见啦，谢谢大家

The Emperor Augustus(, it appears, )commissioned an idealized sculpture portrait, the features of which are so unrealistic as to constitute what one scholar calls an "artificial face."

我的分析是，红色部分为句子主干，括号是插入语，后面是修饰的portrait的从句。

tonect

谢谢，我看懂啦

完了，我刚才是突然傻了，我总觉得后面，the features又是另一个句子的主语了，傻死了，赫赫
