A 15th-century Commonplace book Commonplace book, including Agostino Dati, Elegantiolae , and Giles of Rome, Capitula fidei Christianae , in Latin, manuscript on paper [Italy, second half 15th century, after 1471].A Franciscan ‘vade mecum’ with practical notes on monastic life, formulae of address, a contemporary excerpt from Agostino Dati’s grammatical textbook Elegantiolae (‘the school book par excellence of the second half of the 15th century’), and Giles of Rome’s Capitula fidei Christianae . 145 x 110mm. i + 40 + i leaves, collation: 16 , 2-48 , 510 (of 12, lacking i and ii), varying number of lines in several hands (lacking opening and two leaves after f.30, scribbles and pen trials to a few leaves, marginal staining and foxing, a few edges frayed). Modern suede (a little stained and worn). Provenance : (1) The first and earliest part of the manuscript (ff.1-6) contains useful information for Franciscan monastic life. A mention of Pope Sixtus IV on f.2v indicates that this part was written after the beginning of his papacy in 1471. The section on modes of address (ff.5-6) mentions specific names, e.g. Paolo da Forli, Francesco Marini da Camerino and Cardinal Orsini, but these are likely examples of how to properly address different ranks of person rather than specific people.
