His son, Paul-Émile Botta (1802-1870), was a distinguished traveller and Assyrian archaeologist, whose excavations at Khorsabad (1843) were among the first efforts in the line of investigation afterwards pursued by Layard.
In 1855, Victor Place, Botta's successor tried to send finds from Kish, Khorsabad, Nimrud and from Assurbanipal's palace in Niniveh, 235 cases all in all, from Mosul down the Tigris and the Shatt al-Arab to Basra, where they were to be loaded on a ship bound to Paris.
Notable works in the collection include the famous Megiddo Ivories; various treasures from Persepolis, the old Persian capital; a collection of Luristan Bronzes; a colossal 40-ton human-headed winged bull (or Lamassu) from Khorsabad, the capital of Sargon II; and a monumental statue of King Tutankhamun.
