Most of the artefacts excavated at Hedemünden Fort were shown in the local museum of Northeim, a small town north of Göttingen. Photographing in museums is a challenge, if allowed at all, but I managed to get a few decent pics.
Spear points found at Hedemünden
The iron hasta
points were attached to wooden shafts. In the right upper corner you can see the iron butt spikes of the shaft end, and the yellowish one in the middle of the pic has been left uncleaned after finding to show what the archaeologists deal with. Hasta
points would be more permanently fixed to the shaft than in case of the pila
because those lances are used for stabbing rather than throwing. Same display seen from the other side
The three points in the middle are classified as iaculum
were smaller javelins used by the cavalry.
Below is the drawing of a fully equipped 1st century legionary (taken from one of the tablets at Hedemünden)
The legionary is equipped with the traditional two pila
, and you can clearly see the points differ from the hasta
ones. As Antoninus
describes in the comments to the first post: "The pilum
has a solid pyramidal point at the end of a slender iron shank; the shank is then attached to the wooden haft. The idea is that, when thrown, the pilum
will continue to penetrate whatever it hits, to a greater depth than a spear. It may even punch through a shield and continue into the body of the shield-bearer. Nice, eh?"
Oh yes, very nice - depending what side you're on. *grin*
Edited to add: Here
is a more recent post about pila
, showing a display of pilum
