With this post, I would like to add some brief reflections about the symbolism related to Vulcan. A typical symbol of this Divine Force is surely the hammer. This symbol shows a very complex value because linked to the metallurgic power of this force. The hammer is a typical expression of Vulcan as underground fire, deriving from the Celestial Fire through the thunder, capable to forge, curve and manipulate the metals.
For this reason, the hammer is firstly a symbol of the thunder as link between the Sky and the Earth: it is important to remind moreover that the myth indicates that the Jupiter's thunders are made by Vulcan with his hammer to highlight the strict and continuos relation between Celestial Fire and Underground Fire.
The Vulcan's hammer is the tool by which this force forges the weapons for heroes. Moreover the hammer is a critical symbol wthin the Mysteries of Cabeiri of Samothrace.
The Vulcan's hammer, link between Celestial Fire and Underground Fire, shows the typical shape of Tau to evidence the ctonic symbolism of this tool. With this shape, the Vulcan's hammer describes an unitary Force expressed through a duplicity. It is a polarizing and axial tool in the handle, but having two extremities, poles, branching off from the same axis. For this reason it is very similar to the caduceus: the Vulcan's hammer has two opposite and inverse directions, two hemishperes, two opposite energies like the yin and yang in the chinese tradition.
The Vulcan's hammer has a striking and lightning power both as creating and destruction power: these are opposite implementations of the same force. It is thus symbol of Life and Death, generation and destruction, coagulation and dissolving (solve et coagula).
