English: Mural inside one of the Sengim-aghiz Caves (German: ; traditional Chinese: , pinyin: Shèngjīnkǒu; "Sengim-aghiz" is also referred to as Sengim Gorge) in Chinese Turkestan, depicting a tree with the vine bearing grapes. The cave which contains the mural was perhaps used for meditation because of its small size. The vine motif is closely connected with Manichaeism, V. Arnold-Döben has collected the passages referring to the vine motif in Manichaean literature, and writes: "In going through the passages [where this motif occurs] it is striking that the motif appears almost exclusively in connection with Manichaean church. In imagery, the church is a vineyard ... As the church has its leader or its head, its archegos, thus the vineyard or the vine is cared for by a gardener or tender." — Manfred Heuser & Hans-Joachim Klimkeit (1998), Studies in Manichaean Literature & Art, Leiden: Brill Publishers (p. 309).
