If there are no independent ways to ascertain their age, we are in a circular logic vortex:
" Pre-Isalmic Arabian swords were straight as evidenced by the collection of the Sacred Swords.
The Sacred Swords are Pre-Islamic in origin because they are straight"
The only dating on these swords is the tradition that they belonged to a defined personality. If we cannot be sure that they belonged to that personality, how do we know their dating?
