Original meaning
Originalists of all stripes cite "The Federalist Papers". It is fairly tenuous to suggest that this represents a good source for the original "intent": after all, Alexander Hamilton, who wrote the majority of those essays, was absent for the greater part of the Philadelphia Convention, and John Jay did not attend it at all. However, James Madison, the principal framer of the Constitution also wrote a substantial amount of "The Federalist Papers". Also, to suggest Hamilton and Jay's absence from the convention implies their ignorance as to the Constitution's original meaning is demeaning to those two men and inaccurate. The collected anti-Federalist papers, of course, will be no use at all to a person searching for the original "intent" of the framers. However, as evidence of how a reasonable person at the time would have understood the words of the Constitution, "The Federalist Papers" and the anti-Federalist essays are evidence of direct relevance.
Federalist No. 84
Federalist No. 84 is a political essay by Founding Father Alexander Hamilton, the eighty-fourth and penultimate essay in a series known as The Federalist Papers. It was published July 16, July 26, and August 9, 1788 under the pseudonym Publius, the name which all The Federalist Papers were published. The official title of the work is "Certain General and Miscellaneous Objections to the Constitution Considered and Answered". Federalist 84 is best known for its opposition to a Bill of Rights, a viewpoint that the work's other author, James Madison, disagreed with. Madison's position eventually won out in Congress and a Bill of Rights was ratified on December 15, 1791.
