Résumé	Bayesian chronological modeling refines archaeological chronologies by combining the calibrated probability distributions of individual radiocarbon dates with prior archaeological knowledge — most importantly the stratigraphic order of samples and their grouping into phases — within a single Bayesian model. Rather than treating each date in isolation, the method asks what calendar ages are jointly consistent with all the dates and all the ordering constraints at once, and returns sharpened posterior distributions for each date plus estimates of the start, end, and duration of phases and the timing of events. Formalized by Caitlin Buck and colleagues and made widely usable through Christopher Bronk Ramsey's OxCal software, with the international IntCal calibration curve as input, it has become the standard framework for high-precision archaeological dating.	The Harris matrix is a method for recording and diagramming the stratigraphic sequence of an archaeological site as a partial-order diagram of individually defined contexts. Devised by Edward C. Harris at the Winchester excavations in 1973 and codified in his Principles of Archaeological Stratigraphy, it treats every deposit, cut, and interface as a separate stratigraphic unit and reduces the tangle of physical relationships among them to a minimal directed acyclic graph that expresses only relative temporal order. By distinguishing physical superposition from temporal sequence and stripping away redundant relationships through transitive reduction, the matrix turns the three-dimensional complexity of a dig into a single, auditable diagram. It is the structural backbone of single-context recording and the standard interface between excavation and chronological modeling.
