This triad is in a style typical of the Khmer Empire (802–1431). The Buddha in the middle performs the gesture of meditation and is seated on the coils of a seven-headed serpent whose hoods form a canopy. The two attendants are Four-armed Lokeśvara and Prajñāpāramitā.

This iconography used to be attributed to the story of the Buddha and Mucalinda the serpent king, as related in Theravāda Buddhist texts such as the Abhiniṣkramaṇa Sūtra. However, recent studies suggest that the central seated figure is the Vairocana Buddha, venerated in the esoteric tradition, and that the iconography may relate to the spread of the Sarvatathāgatatattvasaṃgraha tantra in Khmer from the 10th century on. The fact that the two attendant figures are also Esoteric Buddhist deities lends support to this theory.

The black glaze is filled with yellowish-brown radiating streaks, giving the bowl a bright and lively appearance, different from the common and plainer hare’s fur bowls. Near the bottom, the glaze is relatively thick, with broken-ice crackle. The base is not glazed, and the black-brown biscuit can be seen.

　This yuhuchun-style ewer has a flared mouth, flat base, and short ring foot. The handle, positioned slightly below the mouth, attaches to the neck and has a loop. The spout is slightly lower than the upper end of the handle, roughly the height of the upper part of the neck. The vessel is mainly decorated with white inlay, but there is also some black inlaid decoration and some simple incised design. The area between the mouth and the neck are adorned with key frets and grass scrolls, bordered by lines; the shoulder is reverse inlaid with a band of lotus petals with lines above and cloud bands below.  On the belly are two roundels of chrysanthemum surrounded by small circles. The lower part of the body is inlaid with a band of lotus petals, lines dividing the upper and the lower bellies. It is covered with grayish green glaze except for the foot rim and base.

Gandhāra is the name for a historical region that covered parts of present-day Afghanistan and Pakistan. Gandhāran art is strongly influenced by the Hellenistic cultural tradition that was established with the conquests of Alexander the Great, the heyday of which coincided in large part with the rule of the Kuṣāṇa dynasty.

This bodhisattva has carefully defined facial features and wavy shoulder-length locks. He wears a shawl, a waist cloth (dhotī), and sumptuous jewelry. The realistically modeled body is strong and upright.

The gesture of fearlessness and the sacred water flask identify this figure as Maitreya, Buddha of the Future. The many similar extant statues dating from the Kuṣāṇa period attest to Maitreya’s popularity at that time.
