Apollodorus, however, makes a rather neat suggestion: Labdacus, he says, starts with the Greek letter lambda (also called labda) (λ), and the name resembles the word for the letter; this letter follows the Greek letter kappa (K) in the alphabet, and kappa is the first letter of Cadmus' name! Alas, Labdacus' own son did not have a name that began with the next letter of the alphabet, mu (M) but was Laïus, the first husband of Jocasta and the father of Oedipus.
