Artistic reasons While in Italy the artists went back to the shape and taste of the classic art, with a strong desire to "break down" with the Middle Age and therefore there was a flourishing of new works in any field (for instance the study on the mathematical perspective and the work of Brunelleschi and Leonardo), in the rest of Europe it continued to dominate the medieval gothic style, that was abandoned very slowly and only thanks to the contribution of the Italian artists, that finally arrived also to the other European courts.

艺术的理由在意大利艺术家回的形状和味道的经典艺术，具有强烈的愿望"崩溃"的中年，因此是一个蓬勃发展的新的作品在任何领域（例如研究数学的角度和工作的布鲁内和莱昂纳多），在欧洲其他地区继续占主导地位的中世纪哥特式建筑，这是被遗弃的非常缓慢，只有感谢贡献的意大利艺术家，终于抵达还向其他欧洲法院审理。

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。
