About this source

What it is

This is Caesar's own written account of his war against Pompey and the Roman Senate, covering the years 49-48 BCE. It was written in three books and later followed by other accounts covering Caesar's wars in Egypt, Africa, and Spain, though those were written by other authors.

Why it matters

Caesar traveled to Alexandria during this period and became involved in the dispute between Cleopatra and her brother Ptolemy XIII. His own writing is notably quiet about Cleopatra, which tells students something about what Roman leaders chose to record and what they left out.

Look closer

  • Why might Caesar say so little about Cleopatra in his own account of events in Egypt?
  • How might a text written by the person involved differ from one written by an outsider?
  • What does Caesar's choice of what to include tell us about his purpose in writing?
