Introductory presentation of the ‘thesis’ and ‘support’ elements in TheSu XML.

THESISSUPPORT
Examples
  • “Lead is among the naturally cold substances” (Plut., Quaest. conv. 6.5, 691b).a

  • “There are times in which, when bad is present, what is neither bad nor good is not yet bad, and others in which this has already become bad” (Pl., Lysis 217e).a

  • The use of “Lead can produce the most cooling of deadly drugs” as an argumentative premise for “Lead is among the naturally cold substances” (Plut., Quaest. conv. 6.5, 691b).b

  • Menexenus’s question “What do you mean?” as the context that prompts and justifies Socrates’s presentation of the lead white examples (Pl., Lysis 217d).b

Abridged definitioncA thesis is an explicit or implicit instantiation of a proposition in a text, i.e. a minimal declarative sentence representing the stance of its speakers.A support is a segment of text that is presented by its speakers in function of a part of the discourse that is conveyed by the same text. A support can be: argumentative; expository; expansive; contextualizing. These four functions may be cumulative.

[i] a The first ‘thesis’ example is visualised in Figure 1; the second in Figure 2, both are discussed in sec. 4.

b These ‘support’ examples are drawn respectively from the Plutarch and Plato visualisations discussed with Figures 1 and 2 in sec. 4.

c These definitions abridge the technical documentation for the elements THESIS and SUPPORT. For full technical definitions, readers should consult https://alchemeast.eu/thesu/ns/1.0/documentation/TheSu.html, using the table of contents on the left side of the page to focus on the elements thesu:THESIS and thesu:SUPPORT; see also Morrone (2022, pp. 6–13) for a scholarly explanation of the schema.

d For a reader-oriented guide to the main features illustrated by these simplified XML structures, see https://thesu.io/documentation. For the formal schema documentation, readers may consult the same technical documentation referenced in note c and focus on thesu:THESIS and thesu:SUPPORT through the table of contents on the left side of the page. Note that the sequence shown inside sequencesGroup is included only for illustration: ‘sequences’ are not required in the annotation of all ‘theses’, and the two ‘thesis’ examples listed in this table are annotated without ‘sequences’.

Visualised comparison between the TheSu XML annotations of (in green) lead white recipes from Dioscorides, De materia medica 5.88.1, Theophrastus, De lapidibus 55, Plutarch, Quaestiones convivales 6.5, 691b, the replications by Caley & Richards (1956) and Katsaros et al. (2010), and (in purple) procedures modelled from Dioscorides’s first recipe and Theophrastus’s.

Figure 7

Image ‘8.gephi_everything.png’, generated through Gephi (‘Fruchterman Reingold’ layout) from the DOT file ‘8.gephi_everything.dot’, with manually added captions and boxes. Comparative visualisation of the TheSu XML annotations for the passages in Plato, Lysis, 217b–e, Dioscorides, De materia medica 5.81, 5.82, 5.88, Plutarch, Quaestiones convivales 6.5, 690f–691c, Theophrastus, De lapidibus, 55–56, Caley & Richards (1956), and Katsaros et al.
