In Roman times, a five-act structure first appeared based upon Horace's recommendations.
arguments rely upon deductive reasoning--fashioning a general statement that should (in terms of logic) be true, and then applying the argument to a specific instance--i.e., the universal statement comes first, and then specific applications in the real world are expected to match it.
For instance, Psalm 118 in the Douay-Rheims numbering of the Bible (or number 119 in the King James numbering of the Bible) is an abecedarian acrostic, with each stanza headed by one of the letters of the Hebrew alphabet, such as Aleph, Beth, Gimel, and so on. Renaissance examples of acrostic poetry include the preface to Ben Jonson's "The Alchemist."ACT: A major division in a play.
Often, individual acts are divided into smaller units ("scenes") that all take place in a specific location.
Chaucer also wrote acrostics such as his "ABC" (Prior a nostre dame) in his younger days.
Acrostics are also common in Kabbalistic charms and word squares, including the Cirencester word square of Roman origin: in classical Hebrew poetry.
