The Romans had it. At Discovery News:
Willer found traces of the superglue while examining a helmet unearthed in 1986 near the German town of Xanten, on what was once the bed of the Rhine.Hmmm... I saved this as a note a few weeks ago, but forgot to record where I originally read it. Anyhow, I thought it was interesting.
"The helmet, which dates from the 1st century B.C., was given to the museum for restoration. I discovered the glue accidentally, while removing a tiny sample of metal from the helmet with a fine saw. The heat from the tool caused the silver laurel leaves on the helmet to peel off, leaving thread-like traces of the glue behind," Willer said.
Willer was amazed to discover that despite such a long exposure to water, time and air, the superglue did not lose its bonding properties.
