The box plot in this repository is not drawn from a spreadsheet: it is drawn from a graph, and every number in it can be asked for directly. The queries below are editable and run in your browser.

Every query below runs in your browser: the graph is fetched as a static Turtle file and queried with rdflib under Pyodide. There is no endpoint, nothing you type leaves your machine, and an archived copy of this repository stays queryable with no service to keep alive. The first page you open downloads roughly 10 MB of Python runtime; after that the browser has it cached.

• The figure, as a table

  Every row of the box plot, in the order the figure draws them.

  table and interval bars 41 rows when built dated-findspots.rq

• The same answer in CIDOC CRM alone

  No lado: and no time: term appears below, only CIDOC CRM — and it still returns all 41 findspots with their dates.

  table and interval bars 41 rows when built crm-only.rq

• Where the calendar and the arithmetic part company

  The findspots whose interval begins before the year 1. Note that numericPosition and inXSDgYear differ by one: xsd:gYear counts astronomically, so 1 BC is the year 0, whereas the source database counts historically and t…

  table 6 rows when built era-and-scale.rq

• Sharply dated, but not a depot

  Findspots that are tightly dated (qInterval above 0.55) while showing almost no die repetition (qRepetition below 0.2) — each stamp occurs once or nearly once.

  table and scatter plot 14 rows when built two-quality-axes.rq

• Sites with more than one findspot

  Bregenz contributes four separately dated findspots; Colchester, London, Vindonissa and La Graufesenque two each.

  table 5 rows when built findspots-per-site.rq

• What links out, and what does not

  Every site, with its ancient name and its Pleiades identifier where the source has one. The gaps are the interesting part: roughly a third of the sites carry no Pleiades link and most carry no Latin name.

  table 34 rows when built external-identifiers.rq

• The whole corpus against the independent dates

  Everything the method rests on, in one picture. Forty-one dated assemblages as bars, and the five independently dated events as vertical lines across them: two Augustan camps, the naval base at Velsen, Vesuvius, Inchtuth…

  table and timeline with fixed points 46 rows when built corpus-against-fixed-points.rq

• The dates the model was calibrated against

  Five events dated by something other than samian — coins, dendrochronology, a volcano, the historical record — and the assemblage each of them bounds.

  table and interval bars 5 rows when built termini.rq

• In use when Vesuvius erupted

  The findspots whose modelled interval contains AD 79. Not a claim that anything here was destroyed by the eruption — it is the other way round: an independently dated instant is used as a probe, and these are the assembl…

  table and map 6 rows when built contemporary-with-vesuvius.rq

• Every dating against every fixed point

  The whole 41 by 5 grid, counted. Each dating ends before an independent terminus, contains it, or begins after it.

  table and bar chart 5 rows when built terminus-positions.rq

• How much of the order survives a closer look

  The one number the two queries below do not show between them. Every pair of the 41 datings stands in exactly one relation on the modelled interval, so the first row is all 820 pairs.

  table and bar chart 2 rows when built allen-strength.rq

• What came before what — the complete matrix

  Every pair of datings stands in exactly one of Allen's thirteen relations, computed on the modelled interval [eff_start, eff_end] and published under lado:possibly*.

  table and bar chart 12 rows when built allen-possible.rq

• The same question in OWL-Time alone

  No lado: predicate appears below — only OWL-Time's own interval relations. It works, and it deliberately returns FEWER pairs than the query above.

  table and bar chart 6 rows when built allen-time-only.rq

• Why an order stops holding

  The pairs that are ordered on the modelled intervals but not once the evidence is read generously.

  table 25 rows when built allen-unstable.rq

• Everything a map needs, in one query

  Coordinates, interval and colour for each findspot. The point sits on the discovery site rather than the findspot, because that is where the source records it — the four Bregenz contexts share one coordinate, and a map t…

  table and map 41 rows when built map-layer.rq

• How the colours were made

  A colour in a dataset is usually an assertion nobody can check.

  table 4 rows when built colour-axes.rq

• Which method produced these dates

  The parameters are in the graph, not only in the paper. Each dating is generated by an activity, and that activity records the plan it followed — so a consumer can ask what k, τ, t₀ and the era convention were, and which…

  table 1 rows when built provenance.rq

• Closed groups that are also sharply dated

  A figure that is not a figure: the selection criterion runs as a query in the browser and the plot is whatever it returned. Move a threshold and the set of findspots changes in front of you. Built by py/make_talk_figures.py rather than from queries.yaml, because it carries its own plotting code.

  table and scatter plot

All of them on one page: all.html. The plain .rq files are in rq/, and the graph itself is bundle.ttl (0.3 MB).
