Zanabazar square script

Zanabazar's square script is a horizontal Mongolian square script (Mongolian: Хэвтээ Дөрвөлжин бичиг, romanized: Hevtee Dörvöljin bichig or Хэвтээ Дөрвөлжин Үсэг, Hevtee Dörvöljin Üseg), an abugida developed by the monk and scholar Zanabazar based on the Tibetan alphabet to write Mongolian. It can also be used to write Tibetan language and Sanskrit as a geometric typeface.

It was re-discovered in 1801 and the script's applications during its using period are not known. It read left to right, and employed vowel diacritics above and below the consonant letters.
