Cleopatra's Needle on Victoria Embankment pt. 3
The obelisk remained in Alexandria until 1877 when Sir William James Erasmus Wilson, a distinguished anatomist and dermatologist, sponsored its transportation to London from Alexandria at a cost of some £10,000 (a very considerable sum in those days). It was dug out of the sand in which it had been buried for nearly 2,000 years and was encased in a great iron cylinder, 92 feet (28 m) long and 16 feet (4.9 m) in diameter, designed by the engineer John Dixon and dubbed Cleopatra, to be commanded by Captain Carter. It had a vertical stem and stern, a rudder, two bilge keels, a mast for balancing sails, and a deck house. This acted as a floating pontoon which was to be towed to London by the ship Olga, commanded by Captain Booth.[2] (Wikipedia)
