Federal Rule of Evidence 901(a) provides that the requirement of 'authentication . . . as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims.' Rule 901(a) is written, of course, in general terms, but is followed by Rule 901(b) which includes examples of methods by which to authenticate evidence. Rule 901(b)(8) provides that authentication of an ancient document may be supplied by a demonstration that a document is in such condition as to create no suspicion concerning its authenticity, was in a place where, if authentic, it likely would be, and has been in existence 20 years or more at the time it is offered. Ancient documents are admissible into evidence as an exception to the hearsay rule. See United States v. Goichman, 547 F.2d 778, 784 (3d Cir. 1976). See Sokaogon Chippewa Community v. Exxon Corp., 805 F. Supp. 680, 711 n.34 (E.D. Wis. 1992), aff'd, 2 F.3d 219 (7th Cir. 1993), cert. denied, 510 U.S. 1196, 114 S. Ct. 1304, 127 L. Ed. 2d 655 (1994).
