阅读下列材料，回答问题。

材料一 关于米诺牛的希腊神话向人们展示了克里特岛有一座迷宫的传说。1900年，英国考古学家伊文思在距克里特岛首府不远处的克诺索斯遗址出现在人们面前，为研究希腊历史提供了有力的材料。后来他雇用能工巧匠加以修复，今天游人看到的便是装修过的宫殿。但某历史学家认为，伊文思重现的米诺斯宫已不是它的原样，而是直接出自伊文思的相像，不值得肯定。

材料二 某同学陈列了他收集的研究米诺斯宫殿和克里特岛文明的资料：古希腊的《荷马史诗.奥德赛》，伊文思撰写的考古著作《米诺斯王宫》，克里特人创制的线形文字A，当然还有以下图片。

注：图一为克诺索斯王宫出土的牛头型酒具，图二为描绘忒修斯杀死米诺牛故事的希腊陶器花瓶图案。
