a city of India, in the territory of Gwalior, stands on the right bank of the Seepra, 152 miles S.W. of Goonah, 260 S.W. of Gwalior, and 598 W.S.W. of Allahabad; N. Lat. 23. 10., E. Long. 75. 47. It is of an oblong form, 6 miles in circumference, and is surrounded by a wall of stone, with round towers. The houses are very much crowded together, and are for the most part built either entirely of wood, or of a wooden framework filled up with brick, with roofs in some cases sloping and tiled, and in others consisting of terraces, after the eastern fashion. The principal bazar consists of a broad and well-paved street, lined with houses of two stories in height, the lower of which, of stone, contain the shops, and the upper, of brick, form the dwellings. There are in the city four mosques and many Hindu temples; a large and convenient, though not very handsome palace belonging to the Scindia family; and an observatory, built by Jai Singh, Rajah of Jaipur, and minister of Mahomed Schah, Emperor of Delhi (1719-1748). Ojein is one of the seven sacred cities of the Hindus; and from it the degrees of longitude are calculated by the Hindu geographers. It is of great antiquity; being believed to be the place mentioned by Ptolemy under the name of Ozozna. Vikramajit, King of Ojein, who ascended the throne in 57 B.C., was so celebrated in India that the Samvat era, which dates from the beginning of his reign, is still universally used throughout Hindustan; and his son Chandrasen is said to have ruled over the whole of India. Ojein fell into the power of the Mohammedans in 1810. At this time it was the capital of Malwa; and along with this country it afterwards came under the power of the Patans, but was recovered by Akbar in 1561. In the middle of the eighteenth century it was conquered by the Mahrattas, and was regarded as the capital of Scindia's dominions till 1810, when the seat of government was transferred to Gwalior.
