The Riddle of the Sphinx
The Riddle of the Sphinx is a riddle taken from Greek mythology, which Oedipus solved.
The Sphinx was a monster with a woman’s head from the waist up, and a lion’s body from the waist down, who stood at the entrance to Thebes and asked any passerby to solve her riddle. Whoever did not manage to solve the riddle, the Sphinx would squeeze him to death… hence the name: sphigo (σφίγκω) = I tighten up.
The enigma of the Sphinx
According to the Oedipus myth, the riddle of the Sphinx is as follows:
“Which being in the morning stands on four, at noon stands on two, and at night stands on three?”
Oedipus saved the Thebans by answering her question correctly.
The second riddle of the Sphinx
According to another tradition, the Sphinx also told a Second Riddle to Oedipus:
“There are two sisters: one gives birth to the other and, in turn, the second gives birth to the first. Who are the two sisters?’
Oedipus answered her correctly too, making the Sphinx fall into the sea and break into a thousand pieces…
At a crossroads in Thebes, before meeting the sphinx, after an intense argument he kills King Laius, not knowing that he was his father, and after the monster’s victory he is proclaimed king of Thebes, by the temporary king of the city, Creon, and married Jocasta, widow of Laius, not knowing that his new wife was also his mother!
Solutions
The answer given by Oedipus to the first question is that this being is none other than man himself, who at the dawn of his life crawls on all fours, when he is an adult, he walks on his two legs, while at the end of his life he walks on three, since an old man who leans on a cane to help him walk…
The answer given by Oedipus to the second question is that the two sisters are nothing more than day and night, eternally alternating with each other.
