Quam multiplicem usum haec triangulorum doctrina omnibus legitime philosophantibus adferat non solum ad expedite absolvendas, quaecunque in locis terrestribus ac maritimis occurrant, dimensiones, sed etiam ad intelligendos fontes eius disciplinae, quae extructa est a Ptolemaeo et Copernico De revolutionibus orbium caelestium, qui sana rerum intelligentia sunt instructi, in sequenti opere, quod complectitur ordinatam astronomicorum et geomatricorum problematum descriptionem, tanquam in clara luce intueri et experientia infallibili duce deprehendere poterunt. Omnia nunc simul in lucem edita in gratiam matheseos studiosorum per Danielem Santbech Noviomagum. Cum Caes<aris> maiestatis gratia et privilegio. Basileae.’

‘Tractatus Georgii Peurbachii super propositiones Ptolemaei de sinubus et chordis. Sinuum, chordarum et arcuum noticia ad coelestium motuum cognitionem pervalde necessaria existit, ideo de eorum doctrina restat in praesenti perquirendum — Et similiter sciemus quantitates reliquarum chordarum, facilis ergo est secundum praemissorum tenorem chordarum ad suos arcus cognitio.’
