something that has a relation to dactyls.

Anciently there were dactylic as well as spondaic flutes, libiae dactylicae. The dactylic flutes consisted of unequal intervals; as the dactylic foot does of unequal measures.

DACTYLIC Verses are hexameter verses, ending in a dactyl instead of a spondee; as spondaic verses are those which have a spondee in the fifth foot instead of a dactyl.

An instance of a dactylic verse we have in Virgil;

Bis patrececide manus; quin protinus omnia Perlegerent oculis. — Aen. vi. 33.
