Amongst the boys whom Apollon loved, mention is made of a boy named Kyparissos, ‘Cypress’. In all these tales the beautiful boys are doubles of Apollon himself.
Kerényi establishes cypress as the mythological identity of Kyparissos, an Apollonian double-figure whose accidental killing of a sacred stag and ensuing grief encode the archetype of mourning-as-metamorphosis.
