"Steeds of Apollo (Apollo XIII)" is a lithograph by Lumen Martin Winter that depicts the mythological horses that pull Apollo's chariot across the sky. The work combines classical subject matter with the modernist printmaking technique of lithography, reflecting Winter's interest in merging antiquity with contemporary artistic methods. The title's reference to Apollo XIII connects the timeless theme of Apollo's divine steeds to the lunar mission era, suggesting a dialogue between mythological and space age narratives.
