The archetype of this entity was not contained in Σ and, in both the archetype and in Σ, this entity probably began: Incipit prologus libri de mensura orbis terrae. Post congregatam epistolam de questionibus decim artis grammatice cogitavi ut liber de mensura provintiarum orbis terrae sequeretur [...] and apparently ended: [...] nocte bobus requies largitur fine laboris.

The archetype of this entity was not contained in Σ and probably began: In provinciis gallicanis decem quae civitates sint. Provincia lugdunensis prima civitates n. IIII. Metropolis civitas lugdunensium [...]. .
But in Σ, this entity probably began: In dei nomine incipiunt annuntiationes provinciarum urbium grecarum et pinnarum vel gallicanarum cum privilegiis suis. Civitas centroñ tarrentasia. [...] and apparently ended, in both the archetype and in Σ: [...] In provinciis num. XVII civitates numero CXV.
The beginning of the entity in Σ corresponds to the beginning of section 10 in the absent archetype which probably began: In provincia alpium graiarum et poeninarum civitates n. II. civitas centronium darantasia. [...] Σ began at this point and the sequence of the sections in Σ corresponds to sections 10-11, 1-9, 12-17 in the archetype of this entity.

The archetype of this entity was not contained in Σ and probably began: Nomina provinciarum. In italia sedecim. Campania in qua est capua. [...] and apparently ended [...] Valentia. Summa CXII
In Σ this entity probably began: De provinciis. Provinciae italiae sunt XVII. Prima campania in qua est capua.[...] and apparently ended: [...] Quinta valentia. Sexta orcades.

The archetype of this entity was not contained in Σ and copies of the archetype contain various editions of it.
In Σ this entity probably began: De montibus romae. Aventinus mons intra urbem dictus quod rex albanorum aventinus ibi sit sepultus et bello extinctus. [...] and apparently ended: [...] Salaria via romae est appellata quia per eam sabini[ni] sal mari deferebant.

The archetype of this entity was contained in Σ and probably began: De rebus bellicis praefatio. Caelesti semper instinctu felicis rei publicae vestrae commoditas sacratissimi principes [...] and apparently ended: [...] ubi iustitia profitente discernuntur merita singulorum. . It contained 12 pictures.

'Disputatio hadriani augusti et epicteti philosophi' (9)

The archetype of this entity was not contained in Σ and copies of the archetype contain various editions of it which, if entitled, all use the term disputatio, not altercatio.
In Σ this entity began with a picture, probably with the caption Disputatio hadriani augusti et epicteti philosophi. The following text probably began: Altercatio hadriani augusti et epicteti philosophi. Had. D: Quid erit nobis si cinctum solvas [...] and apparently ended: [...] Epic. D: Qui tanquam pisces adescantur.

'De regionibus urbis romae' (10)

The archetype of this entity was not contained in Σ and probably began: Regio I porta capena continet aedem honoris et virtutis [...] and apparently ended: [...] Castra equitum singulariorum peregrinorum ravennatium lecticariorum silicariorum Misenatium tabellariorum victimariorum. Mensae oleariae per totam urbem n.Π.CCC
But in Σ, this entity began with a picture, probably with the caption: Urbs quae aliquando desolata nunc clariosior (B1552 (12) = gloriosior, M10291 (13) = praeclarior) piissimo imperio restaurata. The following text in Σ probably began as it did in the archetype and apparently ended: [...] Castra equitum singulariorum peregrinorum. (11)

'De regionibus urbis constantinopolitanae' (14)

The archetype of this entity was not contained in Σ and probably began: Praefatio. Saepe litteris dediti, quos pro ingenii facultate latentium rerum cura sollicitat [...] and apparently ended in both Σ and in the archetype: [...] latitudo autem pedum sex milia centum quinquaginta.
In Σ, this entity apparently began: Regio prima continet domum placidiae augustae. [...] omitting the entire preface, as well as the introduction to - and first three items in the list of - the regio prima. This suggests the loss, from Σ before 1427, of the opening folio, of which the first page probably contained a picture and the second the opening text.

The archetype of this entity was not contained in Σ and copies of the archetype contain various editions of it.

In Σ this entity probably began: De gradibus. Gradus cognationum appellantur ab eo quod personae cognatorum aliae proximiore aliae longiore gradu sunt et ob id quasi gradatim altera alteram antecedit. [...] and apparently ended: [...] Item sobrini sobrinae, id est qui quaeve ex duobus consobrinis progenerantur.
The text was followed by a page that contained a stemmatic diagram or consisting of 72 squares each inscribed with one of the terms used to describe the male and female descendants, relatives and ancestors within a family over several generations. In the lower half of the page there existed two framed pictures, one to the left and one to the right of the central column of the diagram. Each of these two pictures contained the drawing of a goat.

The archetype of this entity was contained in Σ and probably began: Notitia dignitatum omnium tam civilium quam militarium in partibus orientis. [...] and apparently ended: [...] Ceteri praesides ad similitudinem praesidis dalmatiae officium habent. It contained 89 pictures and occupied approximately half the total number of pages in the codex Σ.

In the codex {O}, two entities were added following the end of its copy of the miscellany [1-13]: namely, (a) Demensuratio provinciarum que non erat in precedenti codice sed de antiquissimo libro excerpta [...] (17) and (b) [...] Ex gregorio Nazianzeno theologo de VII mundi spectaculis Kyriaci Anconitani brevissima in Latinum expositio ad R.P.d.p. donatum [...] (18) which, as the note to (a) states, did not occur in Σ.

It is not known when or where the miscellany comprising the contents of Σ was compiled but, since copies of the miscellany exist only in copies of Σ, it is probable that this codex was also the first to contain it and, for this reason, the miscellany is sometimes referred to as the collectio Spirensis.

The miscellany comprising the contents of Σ was created either when the contents of separate codices were copied into one codex, or when formerly separate codices were bound together within one cover, and the evidence suggests that there were two such separate codices whose contents corresponded to Σ(1-7) and Σ(8-13), and that the first of these codices previously combined the contents of two formerly separate codices whose contents corresponded to Σ(1-4) and Σ(5-7).

The division of the contents of Σ into into thirteen graphic entities is subjective and other divisions have been proposed.

It should be stated that the purpose of any divison of the constituent parts into which any graphic entity can be divided should be to facilitate reference to those parts in any consideration their content, rather than to prejudge the outcome of such a consideration. It is not the intention, in dividing the contents of Σ into thirteen entities in this description, to introduce any such prejudgement.

At the beginning of the 19th century, Morelli (19) divided the miscellany into ten parts, comprising our entities [1, 2-3, 4, 5-6, 7, 8, 9, 10-11, 12, 13] and this division into ten opuscula was accepted by Parthey and Pinder (20) who added, however, that this series opusculorum, quae in codice Spirensi continebatur, in duas dividitur partes of which pars I comprised their five opuscula represented by our entities [1-7] and pars II their five opuscula corresponding to our [8-13]. This division was based on the fact that all of the entities [8-13] in the book Σ were accompanied by pictures, whereas entities [1-7] were not. These two conclusions - about the division of the miscellany into ten opuscula and two partes - were accepted by Pertz (21) and by Grünenwald. (22)

Whereas these writers had proposed a division into ten parts, Böcking identified eleven Stücke corresponding to our entities [1, 2, 3, 4, 5-6, 7, 8, 9, 10-11, 12, 13] (23) and the same division was adopted by Jordan (24) . Jullian also identified eleven textes but disagreed with Böcking concerning their identification, describing the eleven textes as those represented by our entities [1, 2-3, 4, 5-6, 7, 8, 9, 10, 11, 12, 13]. (25)

Next, the miscellany was divided into twelve parts, first by Riese (26) who saw twelve opera in our entities [1, 2-3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]. The same number, but a different division was proposed by Omont (27) , who described the twelve divers opuscules as [1, 2, 3, 4, 5, 6, 7, 8, 9, 10-11, 12, 13] and by Bieler, (28) who defined the texts as being [1, 2, 3, 4, 5-6, 7, 8, 9, 10, 11, 12, 13].

Another group identified thirteen parts, which is the division adopted here: namely, [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]. This was done by Seeck, (29) who called these entities libelli and partes. This division was subsequently adopted by Mommsen, (30) Sabbadini, (31) Neher, (32) Girard, (33) Valentini and Zucchetti, (34) Nordh, (35) and Thompson. (36)

But Schnabel (37) identified fifteen "Schriften" corresponding to our entities [1a, 1b, 2a, 2b, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]. This division of the miscellany was subsequently adopted by Lehmann (38) and by Gottardi. (39) Schnabel had also initially accepted the conclusion, reached by Parthey and Pinder, that the entities comprising the miscellany could be grouped into two larger parts, comprehending the unillustrated entities [1-7] and the illustrated entities [8-12]. But he extended this division by arguing that the earliest codex known to us to have contained the miscellany [1-13] was Σ and that this comprised drei Teilen corresponding to our entitiess [1-7], [8], [9-11, 13], with [12] added later. (40)

In other words, the miscellany has been seen to be comprised of ten, eleven, twelve, thirteen or fifteen partes, libelli, opera, opuscula, texts, Schriften and Stücke and, within these numbers, the proposed entities are not always the same.

The disagreements about the division of the miscellany arise because of different identifications of the original compositions or compilations from which the entities in the miscellany were derived.

The identification of the original compositions or compilations from which the contents of the miscellany in the book Σ were derived is complicated by the fact that almost all those contents did not indicate exactly, or at all, the title of their originals, nor their authors or compilers, or the places and dates of their composition or compilation. Only one of the entities, Σ4, was derived from an archetype that contained the the name of the author of the original composition, together with its date and apparent title.

(O) to RES PVBLICA ROMANA and the caption .DIVVS. AVGVSTVS. PATER. (O) to DIVVS AVGVSTVS PATER PATRIAE) while, at the beginning of his Tomus II: Notitia dignitatum in partibus occidentis, Böcking again printed two pictures, reprinting the first of the earlier two pictures, with the caption RES PVBLICA ROMANA, but replacing the second with the picture which, in Σ, prefaced the text of entity (10a) - except that, this time, Böcking omitted the caption: Urbs quae aliquando desolata nunc clariosior piissimo imperio restaurata.
