Johann Ludwig Burckhardt was a Swiss traveller, geographer and Orientalist. Burckhardt assumed the alias Sheikh Ibrahim Ibn Abdallah during his travels in Arabia. He wrote his letters in French and signed Louis. He is best known for rediscovering two of the world's most famous examples of rock-cut architecture – the ruins of the ancient Nabataean city of Petra in Jordan and the temples of Abu Simbel in Egypt.

Petra, originally known to its inhabitants as Raqmu or Raqēmō, is a historic and archaeological city in southern Jordan. Famous for its rock-cut architecture and water conduit system, Petra is also called the "Rose City" because of the colour of the sandstone from which it is carved; it was famously called "a rose-red city half as old as time" in a poem of 1845 by John Burgon. It is adjacent to the mountain of Jabal Al-Madbah, in a basin surrounded by mountains forming the eastern flank of the Arabah valley running from the Dead Sea to the Gulf of Aqaba. Access to the city is through a famously picturesque 1.2-kilometre-long gorge called the Siq, which leads directly to the Khazneh.
