This dataset consists of one table in CSV format. Each record corresponds to a single ceramic sherd for which weight in grams was measured and recorded together with the stratigraphical context of provenance and a broad category label. All contexts are from the excavation in the Byzantine Quarter near the temple of Apollo Pythios in Gortys, Crete, and are dated to the Late Roman and Early Byzantine period (4th-8th century). A total of 25 contexts is included in the dataset, recorded in the years 2012-2014 during fieldwork seasons. Column descriptions: Weight: weight in grams, recorded with a common electronic kitchen scale capable of measuring 7000±1 g and a minimum of 2 g; Category: a generic label describing the category of ceramic find ‒ most should be self-explaining apart from “Sovradipinta”, a semi-fine painted ware locally produced in Gortys, basically identical to the plain wares. For some records the “Category” field is empty (for reasons of time constraints in the fieldwork season) and should be treated as NA; Context: a numeric identifier for the stratigraphic context of provenance. Measured by: initials of operator who performed the weighing (Stefano Costa, Elisa Triolo, Enrico Zanini, Andrea Bellotti); Notes: notes.
