A brahmin village on the western boundary of Majjhimadesa (Vin.i.197; AA.i.56, 205; MA.397, etc; J.i.49). It was in the Kosala country and belonged to the Mallas, and was once visited by the Buddha.
The people of Thūna were unbelievers and, hearing of the Buddha's contemplated visit, they removed all the boats of the river which the Buddha had to cross, closed all the wells except one and determined not to honour the Buddha in any way.
The Buddha arrived with the monks through the air and a slave-woman, coming to fetch water, saw them and gave them to drink. For this, she was beaten by her husband and killed; but she was reborn in Tāvatimsa.
The Buddha, by his power, caused the water in the wells to overflow and flood the village. The inhabitants begged his forgiveness and invited him and the monks to stay there. Vv.i.8; VvA.45ff.
The Buddha's visit is described at Ud.vii.9 (UdA.377), but no mention is made there of the slave-woman.
A city called Thūna is mentioned in the Mahājanaka Jātaka (J.vi.62, 65).
