The Mah-rui (lit. moon-faced) are two metallic stands about nine inches in height.
They are so-called because they have a moon-faced or crescent-shaped top.
They are also called barsom-dan, because the barsom twigs are placed upon them.
They are the ceremonial instruments referred to as Mah-ruyo in the Dadistan-i Denig (Chap. 48.14).
