Syncrisis

Comparison of two people or things, point by point, to evaluate both.

Syncrisis (Greek synkrisis, 'comparison') sets two subjects side by side and measures them against each other across matched criteria. It was a standard exercise in the progymnasmata, the graded rhetorical curriculum of the ancient schools, and it structures Plutarch's Parallel Lives, where each Greek-Roman pair ends in an explicit comparison.

The figure differs from simple analogy in that both terms are of equal interest. An analogy explains A by means of B; syncrisis judges A and B together, and the judgement is the point.

In quotable form it usually appears as a balanced antithetical sentence, which is why syncrisis and antithesis so often coincide: the parallel grammar makes the comparison auditable in a single breath.

Common mistake: stacking unmatched criteria. If one subject is praised for courage and the other faulted for lateness, the comparison is rhetorical sleight rather than syncrisis.

Example
Demosthenes' power lay in his argument, Cicero's in his charm.
