An insecure Egyptian ruler, bullied as a child for his weight, was persuaded that a canal connecting the Mediterranean to the Red Sea would bring him glory – a monument rivaling those of his more illustrious predecessors.
Said Pasha, ruler of Egypt and Sudan from 1854 to 1863, never saw the completion of the canal, which opened six years after his death. He is remembered as the man who sold the rights to the waterway to the then-imperialist powers France and Britain.
A century and a half later, another Egyptian leader seeking to make his mark on history, President Abdel Fattah al-Sisi, decided to expand the Suez Canal.
Like Said Pasha before him, Sisi sees in the canal a symbol of Egypt's glory and prosperity, and of independence since its nationalisation in 1956.
A canal from the Nile river to the Red Sea existed in the times of ancient Egypt, but was lost over the ages.
The idea was revived by French Consul Ferdinand de Lesseps, who persuaded Said Pasha to grant him a concession for building a waterway.
Spaghetti and the Suez
Said Pasha was an obese child to the severe dismay of his demanding father, the great Mohamed Ali Pasha, who subjected the boy to arduous exercises.
He was befriended by de Lesseps and the consul reportedly sealed the bond with surreptitious plates of spaghetti, according to University of California-LA historian Afaf Lutfi Al-Sayyid Marsot.
"Though Said did become famous it was more for his gullibility in signing an unfavorable concession" that saddled the country, then nominally under Ottoman control, with foreign debt, Marsot has written.
The canal, completed by de Lesseps's Suez Canal Company, opened on November 17, 1869. Thousands of Egyptian workers died digging it.
In 1882, partly worried that the nationalist rebel leader Colonel Ahmed Urabi would seize power, defaulting on the country's debt and taking over the canal, Britain invaded.
The British eventually withdrew from Egypt, leaving behind a pliant monarchy, but they continued to control the Suez Canal Company along with France, something that rankled another Egyptian colonel, Gamal Abdel Nasser.
Nasser was one of the leaders of a popular military coup that toppled the monarchy in 1952, and swiftly became president of the new republic.
Like every great Egyptian leader, or at least every Egyptian leader who aspired to greatness, he forthwith decided on a monumental project, the Aswan Dam.
But the pan-Arabist firebrand could get no foreign funding on his own terms. He increasingly rattled Britain, France and Israel with his support for Algerian rebels and his bellicosity towards the Jewish state.
Suez canal revenues were meanwhile filling other countries' coffers.
On July 26, 1956, the charismatic Nasser gave an address to the nation, railing against the United States, Britain and France and what he denounced as a plot to keep his country subjugated.
Nasser recounted a meeting with the head of the World Bank, Eugene Black, to secure funding for the dam.
"I started looking at Mr Black, as he sat before me on a chair, and I imagined that I was sitting in front of Ferdinand de Lesseps," Nasser said.
The name of the French consul was a codeword to troops to seize the canal.
British premier Anthony Eden and French counterpart Guy Mollet were predictably enraged and began contemplating military intervention.
The fledgling State of Israel was also alarmed at the move, for more existential reasons. In seizing the canal Nasser ordered his troops to shut the Straits of Tiran – blocking it to Israeli shipping at a time when most foreign trade was conduct by sea. The move was seen by Jerusalem as a clear casus belli.
Together with Israeli Prime Minister David Ben Gurion, Eden and Mollet gathered in a villa outside Paris and hatched a plan.
Israel would invade Egypt, and France and Britain would drop troops in a show of intervening, conveniently seizing the Suez Canal in the process. The meeting was detailed in a study by Oxford University historian Avi Shlaim.
The operation began in October 1956, and went smoothly enough for the invaders until the United States, in part seeking to avoid a confrontation with the pro-Nasser Soviet Union, led global efforts that forced France, Britain and Israel to withdraw.
On Thursday, Sisi will inaugurate the new 72-kilometre (45-mile) extension to the canal in a ceremony where he will arrive aboard a refurbished yacht once owned by the former royal family and which carried French Empress Eugenie de Montijo across the canal in the 1869 inauguration.
Sisi ordered the extension to the canal shortly after his election last year, following the 2013 military overthrow of Islamist President Mohamed Morsi, setting off a deadly police crackdown on Islamists and a militant insurgency.
The field marshal-turned-president has intimated that it was nothing less than a divine hand that brought him to power at this point, to restore order and glory to Egypt.
And — though French President Francois Hollande is the guest of honour at Thursday's ceremony — Sisi has left no doubt that now Egypt's hand is on the tiller when it comes to Suez. This time Cairo raised the funds for the canal project domestically.
