Demetrius Lacon in Wikipedia
            Demetrius Lacon or Demetrius of Laconia was an Epicurean philosopher of the late 2nd century BC, and a disciple of Protarchus.[1] He was an older contemporary of Zeno of Sidon and a teacher of Philodemus. Sextus Empiricus quotes part of a commentary by Demetrius on Epicurus, where Demetrius interprets Epicurus' statement that "time is an accident of accidents."[2]
