I thought that statues represented to rulers, their families and important people close to them in ancient era.
My thought is wrong when I read several literatures.
The non royal statues, namely “Memi and Sabu” were found in the non royal cemeteries surrounding the Great Pyramid of Khufu (Cheops) at Giza.
The statues came from dynasty IV or dynasty 4 lasted from around 2613 to 2494 BC. A dynasty characterized as a "golden age" of the Old Kingdom.
It was a time of peace and prosperity, as reported by The Met (2000-2016b) that in respect to culture, this era was flowering with non royal statuary.
In term of statue medium; Memi and Sabu is made of limestone and paint, Alkhalifa (2014) suggested that limestone is a common resource.
In addition to small size of statue, hence, makes it safe to assume that the sculpture was not intended for an extremely wealthy individual.
Social status of Statues was distinguished by medium of stones and clothes they wear.
However, they depicted as a simple human being. Memi is a husband that gives warm embrace to his wife, Sabu.
In contrast, statues of rulers, heroes or very important people were made of diorite, a rock composed principally of the silicate minerals, and depicted with their hands folded in a traditional gesture of greeting and prayer.
Do you know about statues and their social status?
