For the poet of Colophon or Claros, see Antimachus.
Antimachus of Teos was an early Greek epic poet. According to Plutarch, he observed an eclipse of the sun in 753 BC, the same year in which Rome was founded. The epic Epigoni, a sequel to the legend of Thebes, was apparently sometimes ascribed to Antimachus of Teos. However, confusion is possible with the much later literary poet Antimachus of Colophon (c. 400 BC), who wrote an epic Thebais on what must have been an overlapping subject.
