Dienekes or Dieneces (Greek: Διηνέκης, from διηνεκής, Doric Greek: διανεκής "continuous, unbroken"[1]) was a Spartan soldier who fought and died at the Battle of Thermopylae in 480 BC.
Herodotus (7.226) related the following anecdote about Dienekes: ... the Spartan Dienekes is said to have proved himself the best man of all, the same who, as they report, uttered this saying before they engaged battle with the Medes:— being informed by one of the men of Trachis that when the Barbarians discharged their arrows they obscured the light of the sun by the multitude of the arrows, so great was the number of their host, he was not dismayed by this, but making small account of the number of the Medes, he said that their guest from Trachis brought them very good news, for if the Medes obscured the light of the sun, the battle against them would be in the shade and not in the sun.
[2]Herodotus also mentions that Dienekes said many other similar things which made him unforgotten.
[3] Plutarch, writing hundreds of years later, also mentions this comment in his "Sayings of the Spartans", but he attributes it to Leonidas I, Dienekes' general in the battle.
The street east of the Tomb of Leonidas in the modern town of Sparta is named for Dienekes (οδός Διηνεκούς, connecting Θερμοπυλών and Ηρακλειδών).
