Life Dionysius of Chalcis (Διονύσιος ὁ Χαλκιδεύς) was a Greek historian from Chalcis in Euboea, active during the 4th century BCE [1]. He is sometimes called Dionysius Scytobrachion, an epithet shared with another writer, which has caused some confusion in the sources [1][2]. His work focused on the history of Alexander the Great and the Wars of the Diadochi.

Works His only known work is the History of the Diadochi (Ἱστορίαι or Τὰ μετὰ Ἀλέξανδρον), which is not extant but survives in fragments [1][2]. It chronicled the events following Alexander’s death in 323 BCE, likely extending into the early 3rd century BCE.

Significance As a fragmentary historian, Dionysius provides a source for the early Hellenistic period. Later historians, such as Diodorus Siculus, used his work in their own accounts [1][2]. His fragments are collected in Felix Jacoby’s Die Fragmente der griechischen Historiker (FGrHist 72), and his main significance lies in his contribution to the transmission of knowledge about the successor kingdoms.
