Introduction Opposition between Carnival and Lent  "Noster sermo erit de ascensu ad paradisum. Materia erit utilis et bona [...] Cogitanti mihi tempus anni secundum quod vivunt persone mundane magnam invenio differentiam inter tempus carnale, quod finitur hodie, et quadragesime, quod incipit cras, quia differunt sicut ascensus et descensus, volandi in altum et cadendi deorsum. [...] Ecce quomodo tempus carnale est tempus descendendi, sed hoc tempus quadragesime est tempus ascendendi, quia in hoc tempore bonus christianus dimittit vanitates, humiliatur etc restituit, confitetur, facit penitentiam, ieiunat etc. Et incipit hoc tempus cras. Ideo de isto sancto tempore proposui thema: Ecce ascendimus Hirosolimam, id est vitam eternam"; (f. o3v). Allegorical interpretation of music instruments (timpani and chitara) as symbols of lust and avarice.    Main part The body of the sermon builds on the image of Jacob's stairway to heaven (Genesis 28). Its third part elaborates at lenght on the topic “scala est caritas”, where its fifteenth steps are derived from the epistle of that Sunday, namely 1 Corinthians 13, since they were presented by the aposle Paul “qui celum ascenderat” (f. o4v).    Conclusion Exhortation to climb this stairway up, until the death , so to enter in heaven.  Call to those who still have to join the salvific path: “Si vero sit aliquis vestrorum qui non sit in scala bone vite, intret modo, quia nunc incipit tempus scilicet quadragesime: Ecce nunc tempus acceptabile, ecce nunc dies salutis etc."
