The British Library owns a fourteenth-century handwritten book containing four poems considered to be among the finest of the English Middle Ages. The unknown author is referred to as the Pearl Poet after the title of one of the poems in the manuscript. Several theories have been put forward about the Pearl Poet’s identity.
John Massey
One theory suggests that the Pearl Poet was John Massey. John was known to have lived in northwest England, where the poems of the Pearl manuscript were produced. Moreover, the surviving manuscript of John’s poem, “Saint Erkenwald,” is in the same handwriting as the British Library’s manuscript of the poems of the Pearl Poet. These facts make a good argument that the Pearl Poet was John Massey.
Hugh
According to a second theory, the fourteenth-century poet known as little Hugh authored the poems. Historical records indicate the Hugh wrote a poem called “The Adventure of Gawain,” which some have hypothesize is the same as one of the four Pearl Poet poems, “Sir Gwain and the Green Knight” The poems of the Pearl Poet make extensive use of alliteration-pairs of adjacent words that begin with the same consonant sound (for example, large lake)—and it is known that Hugh wrote alliterative verse. The shared subject matter and use of alliteration support the identity of Hugh as the Pearl Poet.
No single author
A third theory argues that the four poems in the manuscript were in fact written by several authors rather than a single one. The only thing all the poems have in common is that they mention places in the same region of England. So perhaps the manuscript represents a collection of poems by several authors from the same region

This week, we will be discussing retail sales. One popular model of retail is “superstores”—very large stores, typically owned by corporations—that sell many kinds of different products. We will compare this business model to local retailers, typically small or specialized stores with local owners, such as a camera shop or a small neighborhood grocery store. Do you think it is more beneficial for people to shop at small local stores rather than at superstores? Why or why?
Andrew
Shopping at small local stores has many benefits for consumers. One of the benefits is that smaller stores often offer better service than larger stores. For example, if you need to repair your bike, usually the small shop can do it in the shop. At the big store, they had to send it to the manufacturer for repair.
Claire
While I understand the importance of shopping in small stores to support the local community, there are also clear benefits to shopping in supermarkets. Because large retailers source products in large quantities, they can offer customers a wide variety of products, often at low prices. Therefore, by shopping at large stores, consumers get their money’s worth.
