An early mausoleum of this type is the mausoleum of Arab-ata, the father of the Arabs in the village of Tim (Narpay district of Samarkand region), possibly so named after one of the Arab commanders. A Kufic inscription with the date 977/978 has been preserved on the building. The Arab-ata mausoleum was built in the same way as the Samanid mausoleum, built of square burnt bricks. The cuboid volume of the Arab-ata mausoleum is completed with a dome, the corners are flanked by octagonal columns. The upper part of the portal with a three-span arcade has suffered from time, but initially its vertical divisions were a fillet, the inscription closed horizontally above the niche. Although the still completely undeciphered inscription of the portal contains the date of the 15th century, the Arab-ata mausoleum is associated with many buildings of the begin-ning of the 11th century with the presence of a portal, its composition, ganch decor on the external and internal surfaces, paired masonry, and the shape of three-blade sails. Probably at the end of the 10th – early 11th centuries. The mausoleum of Mir-Seyid Bakhrom in Kermin (Navoi region) was also built, more modest in size (4.4x4.4 m in the interior), forms and ornamentation of the portal. This is the first of the «facade type» mausoleums known in Central Asia, that is, with the devel-opment of one of the facades in portal forms. Its cuboid volume is covered with a sphero-conical dome on eight arches. It has angular columns of openwork ma-sonry and laying of brick patterns on a ganch background and is associated with the Arab-ata mausoleum.
