The small collection of terracotta and pottery finds, stored in the depository of the Náprstek Museum in Prague, comes from the ancient city of Karakorum in Mongolia. Their origin is connected with the first Czechoslovak-Mongolian expedition led by Dr. Lumír Jisi (1921-1969), whose interests were focused on Mongolian archaeology and Mongolian, Tibetan and Japanese art. In 1958 he was charged with the excavation of prince Kültegin monument in Khöshöö-tsaidam (Arkhangai aimak, Central Mongolia) and within this time he had also undertaken few study journeys round famous Mongolian sites in the valley of Orkhon. One of his surface searches pointed to also to the area of Karakorum and Erdene Zuu monastery, where he gathered some significant pottery sherds, fragments of terracotta statues and other artefacts. These were later in 1984 donated to the Náprstek Museum (inventory 1994) as a part of L. Jisl's estate, held by Mrs. Jislová. [ABSTRACT FROM AUTHOR]
