Ostomachion

Αρχιμήδους <Ὀ>στομάχιον (source: Greek palimpsest, from the Cloister of Saint Sabba [= Mar Saba], Jerusalem, then at Metochion of the Holy Sepulchre, Constantinopole, 1899 - The text is in Heiberg's edition of Archimedes, Opera, 2nd ed., Teubner, Leipzig, 1913, vol. II, pp. 415-424):

(This text is rather incomplete and describes the relationships between various angles of the pieces. Research published by Dr. Reviel Netz of Stanford University in 2003 argued that Archimedes was attempting to determine how many ways the pieces of paper could be assembled into the shape of a square and thus represents an example of an early problem in combinatorics)

D. M. Ausonii 'Cento nuptialis' (bibliographical source: edited & translated by H. G. Evelyn White. Loeb Classical Library. Vol. I, Book XVII: Cento Nuptialis):
[...] Accipe igitur opusculum de inconexis continuum, de diversis unum, de seriis ludicrum, de alieno nostrum, ne in sacris et fabulis aut Thyonianum mireris aut Virbium, illum de Dionyso, hunc de Hippolyto reformatum. Et si pateris, ut doceam docendus ipse, cento quid sit absolvam. Variis de locis sensibusque quaedam carminis structura solidatur, in unum versum ut coeant aut caesi duo aut unus et sequens cum medio, nam duos iunctim locare ineptum est et tres una serie merae nugae. Diffinduntur autem per caesuras omnes, quas recipit versus heroicus, convenire ut possit aut penthemimeris cum reliquo anapaestico aut trochaice cum posteriore segmento aut septem semipedes cum anapaestico chorico aut <ponatur> post dactylum atque semipedem quidquid restat hexametro, simile ut dicas ludicro, quod Graeci «ostomachion» vocavere. Ossicula ea sunt: ad summam quattuordecim figuras geometricas habent. Sunt enim aequaliter triquetra vel extentis lineis vel <eiusdem> frontis, <vel aequicruria vel aequilatera, vel rectis> angulis vel obliquis: isoskele ipsi vel isopleura vocant, orthogonia quoque et scalena. Harum verticularum variis coagmentis simulantur species mille formarum: helephantus belua aut aper bestia, anser volans et mirmillo in armis, subsidens venator et latrans canis, quin et turris et cantharus et alia huiusmodi innumerabilium figurarum, quae alius alio scientius variegant. Sed peritorum concinnatio miraculum est, imperitorum iunctura ridiculum. [...] (Ausonius compares here the Ostomachion to a form of poetry in which various meters are jumbled together)

Caesii Bassi sive Atilii Fortunatiani fragmentum 'De Metris' (bibliographical source: H. Keil, Grammatici Latini, Volume VI, Hildesheim, 1961):

[...] Habet autem metrorum contemplatio, si exercitatio accessit, in cognoscendo voluptatem, cum et quaecumque dicuntur metra celeriter intellegamus unde sint et qua ratione composita, et multa ipsi nova excogitare possimus. nam si loculus ille | Archimedius, <qui> quattuordecim eboreas lamellas, quarum varii anguli sunt, in quadratam formam inclusas habet, componentibus nobis aliter atque aliter modo galeam, modo sicam, alias columnam, alias navem figurat et innumerabiles efficit species, solebatque nobis pueris hic loculus ad confirmandam memoriam prodesse plurimum, quanto maiorem potest nobis adferre voluptatem quantoque pleniorem utilitatem carmina inter manus habentibus metrorum varia tractatio, cum subinde apud poetas ea quae fallunt imperitos metra inserta numeris et intermixta carminibus || hac arte deprehendemus? de quibus in his libris explicabimus, quos de melicis poetis et de tragicis choris scripturi videmur, quibus necesse erit etiam graeca interponere exempla, quod ne faceremus in hoc libro elaboravimus. nam si volumus de omni ratione carminum dicere, necesse est ad eorum copias manum porrigamus, qui cum essent non tantum poetae perfectissimi sed etiam musici, sine magno labore praeparatis utebantur facultatibus. [...] (Bassus reports that the combinatorial puzzle game was played by children as it was supporting their memory)

Marii Victorini 'Ars grammatica' (bibliographical source: p. 100 in the edition of Keil. Given in Archimedes Opera II, 2nd ed., 1913, p. 417):
[...] nam ut in illo praefinito ac determinato crustarum numero multiplici earundem varietatum specie nunc navis, nunc gladius, nunc arbuscula et siqua alia figurantur, ita metrorum certo ex origine numero intra decem prototypa comprehenso multiplex admodum varietatis copia propagatur. [...]
