The Friday Mosque in Herat, Afghanistan.
Here, calligraphy blends with other forms of decoration. The upper sides contain the "Thuluth" (literally: One Third, and called so because the horizontal part of the letter is usually one third the height of the vertical part). The bottom part contains four lines in "Nasta 'liq". Other decorations are done in "Kufie" and N"Naskhi" scripts.
