Moonstone Arts Center's Winter Solstice anthology returns for 2026, organized around the astronomical and symbolic threshold of the year's longest night. The call is deliberately narrow in form: one poem per poet, no more than 35 lines, with stanza breaks, section breaks, and epigraphs counted toward the limit. This is a themed anthology rather than an open-topic magazine issue, and the curatorial premise is the solstice itself—its darkness, its reversal, its recurrence in both hemispheres. The center's anthology tradition positions the project between a literary magazine and a commemorative volume: poems are selected for a specific seasonal occasion and presented together as a coherent reading experience. Accepted poets receive publication in the 2026 anthology and the opportunity to participate in a virtual event on December 20, 2026. There is no cash prize and no stated honorarium; the compensation is publication and inclusion in the reading. The editorial vision favors work that engages the solstice with precision rather than generality. The prompt's own language—polar darkness, maximum tilt, the shortest period of daylight—suggests that successful submissions will treat the solstice as a physical and emotional fact, not merely a seasonal greeting. Poets working in formal or free verse, lyric or narrative modes, are equally viable provided the poem earns its place within the 35-line constraint.
