QUES: Its knowledge and uses spread from China through the Middle East to medieval Europe in the 13th century, where the first water powered paper mills were built. Because of paper's introduction to the West through the city of Baghdad, it was first called bagdatikos. In the 19th century, industrial manufacture greatly lowered its cost, enabling mass exchange of information and contributing to significant cultural shifts. In 1844, the Canadian inventor Charles Fenerty and the German F. G. Keller independently developed processes for pulping wood fibres.

QUES: While worship in the Temple in Jerusalem included musical instruments (2 Chronicles 29:25–27), traditional Jewish religious services in the Synagogue, both before and after the last destruction of the Temple, did not include musical instruments given the practice of scriptural cantillation. The use of musical instruments is traditionally forbidden on the Sabbath out of concern that players would be tempted to repair (or tune) their instruments, which is forbidden on those days. (This prohibition has been relaxed in many Reform and some Conservative congregations.) Similarly, when Jewish families and larger groups sing traditional Sabbath songs known as zemirot outside the context of formal religious services, they usually do so a cappella, and Bar and Bat Mitzvah celebrations on the Sabbath sometimes feature entertainment by a cappella ensembles. During the Three Weeks musical instruments are prohibited. Many Jews consider a portion of the 49-day period of the counting of the omer between Passover and Shavuot to be a time of semi-mourning and instrumental music is not allowed during that time. This has led to a tradition of a cappella singing sometimes known as sefirah music.

QUES: In the Late Empire and Middle Ages Vergilius was spelled Virgilius. Two explanations are commonly given for this alteration. One deduces a false etymology associated with the word virgo ("maiden" in Latin) due to Virgil's excessive, "maiden"-like modesty. Alternatively, some argue that Vergilius was altered to Virgilius by analogy with the Latin virga ("wand") due to the magical or prophetic powers attributed to Virgil in the Middle Ages (this explanation is found in only a handful of manuscripts, however, and was probably not widespread). In Norman schools (following the French practice), the habit was to anglicize Latin names by dropping their Latin endings, hence Virgil. In the 19th century, some German-trained classicists in the United States suggested modification to Vergil, as it is closer to his original name, and is also the traditional German spelling.[citation needed] Modern usage permits both, though the Oxford guide to style recommends Vergilius to avoid confusion with the 8th-century grammarian Virgilius Maro Grammaticus. Some post-Renaissance writers liked to affect the sobriquet "The Swan of Mantua".[citation needed]
