In the early 19th century the foundations for the extensive collection of sculpture began to be laid and Greek, Roman and Egyptian artefacts dominated the antiquities displays. After the defeat of the French campaign in the Battle of the Nile, in 1801, the British Museum acquired more Egyptian sculptures and in 1802 King George III presented the Rosetta Stone – key to the deciphering of hieroglyphs. Gifts and purchases from Henry Salt, British consul general in Egypt, beginning with the Colossal bust of Ramesses II in 1818, laid the foundations of the collection of Egyptian Monumental Sculpture. Many Greek sculptures followed, notably the first purpose-built exhibition space, the Charles Towneley collection, much of it Roman sculpture, in 1805. In 1806, Thomas Bruce, 7th Earl of Elgin, ambassador to the Ottoman Empire from 1799 to 1803 removed the large collection of marble sculptures from the Parthenon, on the Acropolis in Athens and transferred them to the UK. In 1816 these masterpieces of western art were acquired by The British Museum by Act of Parliament and deposited in the museum thereafter. The collections were supplemented by the Bassae frieze from Phigaleia, Greece in 1815. The Ancient Near Eastern collection also had its beginnings in 1825 with the purchase of Assyrian and Babylonian antiquities from the widow of Claudius James Rich.
