I went to Rome and all I got was this lousy pen

The photo shows four images of the same Roman iron stylus pen, one below the other. The knib to the left. It has an inscription which runs along its length on four sides. The four images show the four lines of inscribed text which read:

‘ab urbe ve]ni] munus tibi
\ gratum adf(e)ro
aculeat]um ut habea]s memoria]m nostra(m)
rogo si fortuna dare]t quo possem
largius ut longa via ceu sacculus est (v)acuus’

‘I have come from the City. I bring you a welcome gift
\ with a sharp point that you may remember me.
I ask, if fortune allowed, that I might be able (to give)
\ as generously as the way is long (and) as my purse is empty.’

The pen was used to write on wax-filled wooden writing tablets. Found in London (Roman ‘Londinium’) by MOLA. Photo by Juan Jose Fuldain/MOLA
