Triads (groups of three ๐ผ) were popular among ancient Egyptian statuary and mythology. This piece from the Louvre is called the โRoyal and Divine Triadโ (Dynasty 19, New Kingdom c. 1279-1203 B.C.E.) because it represents three ๐ผ of the most powerful figures in the Egyptian pantheon. Rameses II ๐๐ ๐๐๐ณ๐บ๐๐ด๐ or his son ๐ ญ Merenptah ๐ณ๐๐๐๐น๐น๐น is on the left, Osiris ๐น๐จ๐ญ is in the middle, while Horus ๐ ๐ญ is on the right. The pharaoh ๐๐ป was viewed as a god ๐น on Earth, Horus ๐ ๐ญ was the king of the gods ๐น๐น๐น, and Osiris ๐น๐จ๐ญ was lord ๐ of the afterlife.

I find this piece super interesting because the pharaoh ๐๐ป kind of inserted himself amongst the most famous of the Egyptian triads – Isis ๐จ๐๐ฅ, Osiris ๐น๐จ๐ญ and Horus ๐ ๐ญ – who were supposed to represent the divine family (mother ๐ ๐๐, father ๐๐๐, and child ๐๐๐). In some instances (like with this statue), the pharaoh ๐๐ป would function as the child in the statue.
Not all triads represented families, though that was the most common. Ptah ๐ช๐๐๐ฑ, Sekhmet ๐๐๐ ๐๐, and Nefertem ๐ค๐๐๐๐๐ฏ was a family triad that was extremely popular in Memphis. During the New Kingdom (around the time of Tutankhamun ๐๐ ๐๐๐ ฑ๐๐น๐พ๐บ๐), the triad of Amun ๐๐ ๐, Ra ๐ณ๐บ๐, and Ptah ๐ช๐๐๐ฑ became very popular due to the powerful nature of these three ๐ผ deities
