Abstract

Pliny the Elder in Natural History, xiii, 74–82, described in detail specifications for the manufacturing of papyrus. However, there was a spurious omission pertaining to the height of the manufactured sheet in sentence 78. Johnson has listed the different theories explaining this as an oversight or that a standard height-to-width ratio existed, thus making the specification of the height redundant. The latter is not substantiated by the measurement of the dimensions of extant papyrus rolls. Johnson proposed a more rational theory, that it was most important to specify the width but this does not explain the absence of any specification of height, even as a measurement of secondary importance.
