Note 557 — EPIGRAMS BY J[ohn] D[avies].
Reading edition
In Titus Andronicus, v. 1, we have the expression "to fight at head" ("As true a dog as ever fought at head"). "To fly at the head" was equivalent to "attack;" and in Nares' Glossary (ed. Halliwell) the expression "run on head," in the sense of incite, is quoted from Heywood's Spider and Flie, 1556.
