> PHerc. 1667 is what survives of a larger roll: earlier attempts to open it by hand — in the nineteenth century, and again in 1969 and the 1980s — destroyed its outer layers and left only the compact inner core, about 8 cm of an original height of 19–24 cm.

I can understand in the freewheeling days of the 19th century, but I'm rather surprised that they'd be so cavalier in the 70s and 80s...
