The mention made of 'Vulcan           with the blue-eyed
maid,' alludes to the olive and the fire, which are found there in
close proximity: for, in a sacred precinct surrounded by a wall, olive
trees are seen to flourish, while fire issuing from their roots burns
among the branches, and with its ashes benefits the tree; hence there
exists a mutual friendship, and Minerva shuns not Vulcan.
