The historic illustrations included in this project were originally published during the late nineteenth and early twentieth centuries. Many originally appeared in publications that predated the widespread use of photography for art documentation. These engravings, line drawings, and plans reflect both the technological and aesthetic standards of their time. By their very nature, they often represent subjective interpretations of the monuments and works depicted, and as such they offer fascinating insights into the cultural values of art and architectural history during the formative years of these disciplines. In the context of these images the terms ""reconstruction"" and ""rendering"" have been used to distinguish between the artists' speculative reconstruction of a ruined work from the artists' perspective drawing or rendition of the design.
