Excerpt from a recent English Chinese translation homework assignment:
The size of a single sheet of papyrus was not constant in ancient times. For most non-literary documents (letters, accounts, receipts, etc.) a single sheet was sufficient; for longer texts, especially literary ones, sheets were stuck together and made into a roll. Rolls have been found measuring as much as 45 yards long. It was usual to write on only one side. Writing on both sides of the sheets of a papyrus roll is quite rare, probably because the delicate material can be torn so easily.
I regularly check assignments against Google translate and the result this time was especially entertaining:
I especially like the 45 yard long Rolls Royce.
