Soon after this the courageous explorer Arnaud discovered the ancient Mariab, the royal city of the Sabaeans, and at great risk copied fifty-six inscriptions and took a plan of the walls, the dam, and the temple to the east of the city.
The famous dam of Ma'rib and its sluices were the work of this ancient prince - structures which Arnaud in the 19th century found in the same state in which Hamdani saw them a thousand years ago.
The ruins of the city of Ma'rib, the old Sabaean capital, have been visited by Arnaud, Halevy and Glaser, but call for further description, as Arnaud confined himself to a description of the dike (see below), while Halevy and Glaser were interested chiefly in the inscriptions.
In 1854 he was promoted general and appointed to the command of the English troops sent to the Crimea (see Crimean War) in co-operation with a strong French army under Marshal St Arnaud and afterwards, up to May 1855, under Marshal Canrobert.
