As we move into the digital epoch of the prime illusion, holography, patently awaits its devenir to further a vision in Art that may be traced back to the invention of perspective by Italian architect, Filippo Brunelleschi, in the middle of the fifteenth Century when he carried out a series of optical experiments that led to a mathematical theory of perspective, to contemporary science where Stephen Hawking suggest that quantum physics conspires the development of a holistic theory of our universe suggesting the universe may be compared to one giant hologram as the information of the whole exists in every constituent part; each particle containing all information pertaining to everything that exists or ever will exist.

当我们迈进数码时代的时候，原始的幻影，全息术，理所当然的期待着它对进一步提高视觉艺术所做的贡献。视觉-作为一种艺术可以从十五世纪中期意大利建筑师费里波。布朗勒斯奇对透视的发明，追溯到当代最新科学中史蒂芬。霍金提出的以量子物理学为基础的宇宙整体理论，前者在当时实现了一系列光学实验从而推导出了透视的数学理论，后者则将宇宙比喻为一张巨大的全息图，因为其全部信息存在于每个要素局部中；每个粒子都包含了属于每件事物的所有信息，无论该事物已存在或是将要存在。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
