During the first half of the ninetieth century, there were diverse styles that were used by various graphic designers. Several examples are Greek, Roman, Classical, Egyptian, and Gothic. The early part of the century has often been regarded as being lackluster for reviving historic styles. However, the latter part of the century would showcase designers using these existing styles as a conceptual framework to expand their own styles. For instance, designer Augustus W.N. Pugin has a quote in the book "The True Principles of Pointed or Christian Architecture" (1841) that says Gothic is "not a style, but a principle."
