Sparticus, what a misadventure that of your cousin! Iīve heard similar stories, like to use archaeological vessels as target by workers at a gravel plant.
Hobb and Yurek, Ah guys... what do you say ?? ???
... to throw or recast my precious glandes!!... with the ballistic information they have, and also the hidden stories they can own. They can have killed a Roman or can have been thrown by a long Balearic sling and surmonted the present distance record of distance. Some of them have a crush point that is telling they have flown point-first, but others have no marks and even a group of them have been not thrown and looks completely perfect, all identical, from the same cast. Others have been remolded by hammer in differents ways to get special effects. Someones are very little, less than 20 gr and others, the Romans specially, are big, but the biggest is about 100 gr. Someones have very elongated points but others are paunchy or barrel shaped.
If someone in the forum have got some glandes it would be interesting to know information about size, shape, etc.
