Holy Lance
The Holy Lance, also known as the Lance of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, according to the Gospel of John, is the lance that pierced the side of Jesus as he hung on the cross.
Spear
In classical Greek mythology Zeus' bolts of lightning may be interpreted as a symbolic spear. Some would carry that interpretation to the spear that frequently is associated with Athena, interpreting her spear as a symbolic connection to some of Zeus' power beyond the Aegis once he rose to replacing other deities in the pantheon. Athena was depicted with a spear prior to that change in myths, however. Chiron's wedding-gift to Peleus when he married the nymph Thetis in classical Greek mythology, was an ashen spear as the nature of ashwood with its straight grain made it an ideal choice of wood for a spear.
