Some claim that the floor of the basilica is the original from the temple of Diana. (Pichey, 80) However, I think that some of the elements in the floor may have come from the temple of Diana, but it is unlikely that the entire floor was that of the earlier temple.  In the picture on the right three very different styles can be seen adjacent to each other.  The small white tiles look as though they could be 1st or 2nd century, while the colorful geometric pattern in the upper right corner of the photo is clearly a later design.  I am not certain about the pattern in the bottom right of the picture.
