The dictionary defines it as an intricate problem; especially: a problem insoluble in its own terms, usually used in the phrase "cut the Gordian knot." But its origins are historical, dating from the time of Alexander the Great.
The story goes that the father of gods had ordained that when it came time for the people to select a king, they must choose the first person to ride up to the temple of Zeus in a wagon. A peasant, Gordius, innocently fulfilled the oracle and was made king. One of Gordius's first acts was to dedicate his wagon to Zeus and to place it near the temple, the yoke tied to the pole by an intricate knot of cornel bark. Another oracle declared that anyone who succeeded in untying the knot would be the conqueror of all Asia. The knot stayed tied until the arrival of Alexander the Great. However, he cheated on the oracle by cutting the knot with his sword instead of untying it. Zeus honored his initiative by making the prophecy come true.
Alexander was reputedly a strong, handsome commander with one eye dark and one blue, always leading his army on his faithful stallion Bucephalo. Alexander III of Macedon died in his 33rd year, and had reigned for 12 years and eight months.
By some accounts, Alexander was bisexual. A book of fiction that we can recommend about this charismatic leader is "The Persian Boy" by Mary Renault, which is told from the point of view of a young eunuch, who falls in love with Alexander as he accompanies him on Alexander's trek.
In our tale, the meaning of the title is multi-layered. We will say no more, other than the knot is not sliced through, but cut in bits and pieces, slowly, so slowly. Enjoy the ride.
