"M. Giorgio de Chirico has just bought a red rubber glove"—so wrote the French poet Guillaume Apollinaire in July of 1914, noting the purchase because, he went on to say, he knew the glove's appearance in de Chirico's paintings would add to their uncanny power. Implying human presence, as a mold of the hand, yet also inhuman, a clammily limp fragment distinctly unfleshlike in color, the glove in The Song of Love has an unsettling authority. Why, too, is this surgical garment pinned to a board or canvas, alongside a plaster head copied from a classical statue, relic of a noble vanished age? What is the meaning of the green ball? And what is the whole ensemble doing in the outdoor setting insinuated by the building and the passing train?
Unlikely meetings among dissimilar objects were to become a strong theme in modern art (they soon became an explicit goal of the Surrealists), but de Chirico sought more than surprise: in works like this one, for which Apollinaire used the term "metaphysical," he wanted to evoke an enduring level of reality hidden beyond outward appearances. Perhaps this is why he gives us a geometric form (the spherical ball), a schematic building rather than a specific one, and inert and partial images of the human body rather than a living, mortal being.
