Reading historical sources
A primary source brings you close to a historical witness, but it still needs interpretation. Ask who wrote it, for whom, in which language, and for what purpose. Notice an edition’s translation choices, omissions, and uncertain attributions. A short quotation can mislead when separated from its argument; read before and after the passage and compare other evidence.
