2. Connected with a literary cycle: specifically applied to certain ancient Greek poets (sometimes inclusive of Homer) who wrote on the Trojan war and the adventures of the heroes connected with it. See cycle, 5.
3. In ancient metrics, delivered more rapidly than usual, so as to occupy only three times or moræ instead of four: used to note certain dactyls and anapests. Thus, a cyclic dactyl is equivalent in time to a trochee, and a cyclic anapest to an iambus.
4. n. A cyclic poem.
5. In chem., containing a cycle or ring.
6. In botany, arranged in whorls: said of the stamens, petals, etc., in a flower; also, having the parts so arranged: said of the flower; cyclical.

7. In geometry, having its vertices all on the same circle: thus, if a quadrilateral has its vortices concyclic it is cyclic.
