Hill-country (hieroglyph)
The ancient Egyptian hill-country hieroglyph is a member of the sky, earth, and water hieroglyphs. A form of the hieroglyph in color, has a green line-(banding) at the base of the hieroglyph. The hieroglyph refers to the hills, and mountains, on both sides of the Nile River, and thus the green references the verdant black farming land adjacent to the river proper.
Various colors, and patterning, may adorn the rest of the hieroglyph when the bottom is green.
