Which term describes the main part of the monument where inscriptions are found?

The term that describes the main part of the monument where inscriptions are found is "Die" or "tablet." The die typically refers to the central portion of a monument, whether a gravestone or a memorial, that is designed to hold inscriptions, such as the name of the deceased, dates, and often a brief epitaph. This part is critical because it conveys the essential information about the individual commemorated by the monument.

The inscriptions are deliberately placed on the die to ensure visibility and to serve their function of memorialization. The die is often raised above the ground level and situated above the base of the monument, allowing it to be easily read by visitors.

In contrast, the other terms provided have distinct meanings. A marker typically refers to a smaller plaque or stone that indicates a grave location or specific information but does not constitute the main part of a larger structure. A memorial encompasses the entire structure dedicated to an individual or event, and a base refers to the foundation or support on which the die (tablet) sits, rather than the part containing inscriptions itself. Thus, "Die (tablet)" accurately identifies the specific section responsible for conveying commemorative messages.
