Marble tomb of Olivar Mistrot 6/6 ...

The image presents a striking visual comparison of two photographs taken at different times. The top photograph shows the marble tombstone of Olivar Mistrot in its natural state, exposed to regular daylight, while the bottom photograph was captured when illuminated by a 365 nm ultraviolet (UV-A) blacklight.

**Image Details**

* **Tombstone:** Made of white marble, with engravings and inscriptions that are partially worn away due to weathering.
   + The top inscription reads: "June 6, 1872 - May 14, 1877."
   + The bottom inscription states: "Children of Hy.B.& M.A. Mistrot."
* **UV-A Blacklight Illumination:** A 365 nm UV-A blacklight was used to illuminate the tombstone.
   + The blacklight causes fluorescent effects on certain areas of the marble.
   + The inscriptions and engravings become more visible under UV-A light.

**Visual Comparison**

The two photographs highlight the difference in visibility between the regular daylight exposure and the UV-A blacklight illumination. The blacklight reveals additional details, such as:
* Fluorescent effects on the marble surface.
* More distinct inscriptions and engravings.

Overall, the image demonstrates how different lighting conditions can affect our perception of historical artifacts like tombstones. – AI vision
