Publilius Syrus (Wikipedia)Publilius Syrus (fl. 85–43 BC), was a Latin writer, best known for his sententiae. He was a Syrian from Antioch who was brought as a slave to Roman Italy. Syrus was brought to Rome on the same ship that brought a certain Manilius, astronomer - not the famous Manilius of the 1st century AD (see Pliny, NH X, 4-5), and Staberius Eros the grammarian. By his wit and talent, Syrus won the favour of his master, who granted him manumission and educated him. He became a member of the Publilia gens. Publilius’ name, due to the palatalization of ’l’ between two ‘i’s in the Early Middle Ages, is often presented by manuscripts (and some printed editions) in corrupt form as ‘Publius’, Publius being a very common Roman praenomen.
Commonplace book (Wikipedia)Commonplace books (or commonplaces) are a way to compile knowledge, usually by writing information into books. They have been kept from antiquity, and were kept particularly during the Renaissance and in the nineteenth century. Such books are similar to scrapbooks filled with items of many kinds: sententiae (often with the compiler’s responses), notes, proverbs, adages, aphorisms, maxims, quotes, letters, poems, tables of weights and measures, prayers, legal formulas, and recipes. Entries are most often organized under subject headings and differ functionally from journals or diaries, which are chronological and introspective." Commonplaces are used by readers, writers, students, and scholars as an aid for remembering useful concepts or facts; sometimes they were required of young women as evidence of their mastery of social roles and as demonstrations of the correctness of their upbringing. They became significant in Early Modern Europe.
