The white seashell is carved in relief with a mandala (Tibetan: dkyil 'khor), a sacred graphic symbol of complex structure, which is interpreted as a model of the Universe in Buddhism and Hinduism. The mandala is additionally set with small coral and turquoise cabochons. The rest of the seashell surface is dull polished and engraved with a Tibetan inscription. All copper mounts, namely a cup-shaped mouthpiece, a wide wing, a conical tip and a large spherical knob, are chased and engraved with floral and geometric motifs. Stylized lotus flowers on the mouthpiece and knob, as well as geometric borders on the tip and wing are highlighted with gold. On the obverse side of the wing, there are images of a dragon and Eight Auspicious Symbols of Buddhism or ashtamangala (Tibetan: bkra shis rtags bryad), which are also gilded. Some of these symbols are repeated on the mouthpiece and wing. The reverse side of the wing is stamped with a large round medallion containing a floral ornament on the circumference and a "wheel of joy" or anandachakra (Tibetan: dga' 'khyil) in the centre.
COMMENT. The presented item is a Tibetan Buddhist ceremonial trumpet called dungkar (Tibetan: dung dkar). It is traditionally used as a musical instrument in various religious and magical rituals, for example, to invoke spirits or banish evil. The "classical" dungkar constitutes a metal-mounted white seashell. Actually, the Tibetan term "dung dkar" is applied to the shell of a large marine gastropod species Turbinella pyrum, which is known as shankha in Hindu mythology. The extremely rare and especially valuable right-turning white conch shell (Tibetan: dung dkar g.yas `khyil; Sanskrit: dakshinavarti shankha) is one of the Eight Auspicious Symbols of Buddhism (Tibetan: bkra shis rtags bryad; Sanskrit astamangala). In addition to the white seashell, this sacred set also includes a jeweled parasol, a pair of golden fish, a treasure vase, a lotus flower, an endless knot, a victorious banner, and a golden wheel or dharmachakra. They represent the offerings of the great Vedic gods to Shakyamuni Buddha upon his attainment of enlightenment.
