Woodbridge entitled "Acoustic Recordings from Antiquity" in its August 1969 edition. In this letter, the author called attention to what he called "Acoustic Archaeology" and described some early experiments in the field. He then described his experiments with making clay pots and oil paintings from which sound could then be replayed, using a conventional record player cartridge connected directly to a set of headphones. He claimed to have extracted the hum of the potter's wheel from the grooves of a pot, and the word "blue" from an analysis of patch of blue colour in a painting. In 1993, the idea was furthered explored by archeology professor Paul Åström and acoustics professor Mendel Kleiner who reported that they could recover some sounds from pottery, mainly in the upper frequencies. As discussed in an episode of MythBusters (Episode 62: Killer Cable Snaps, Pottery Record) while some generic acoustic phenomena can be found on pottery, it is unlikely that any discernible sounds (like someone talking) could be recorded on the pots, unless ancient people had the technical knowledge to deliberately put the sounds on the artifacts. In popular culture Nigel Kneale's 1972 BBC television play The Stone Tape helped to popularize the term 'stone tape theory'. Arthur C. Clarke discussed the idea at a NASA conference on the future of technology in the early 1970s. An episode of Mysteryquest on History called Stonehenge featured Rupert Till and Bruno Fazenda conducting acoustic tests at Stonehenge and at the Maryhill Monument, a full-sized replica of Stonehenge in the USA. Gregory Benford's 1979 short story "Time Shards" concerns a researcher who recovers thousand-year-old sound from a piece of pottery thrown on a wheel and inscribed with a fine wire as it spun. The sound is then analyzed to reveal conversations between the potter and his assistant in Middle English. Rudy Rucker's 1981 short story "Buzz" includes a small section of audio recovered from ancient Egyptian pottery. A 2000 episode of The X-Files, "Hollywood A.D.", features "The Lazarus Bowl", a mythical piece of pottery reputed to have recorded on it the words that Jesus Christ spoke when he raised Lazarus from the dead. In the 1996 game Amber: Journeys Beyond, this phenomenon is referred to as 'stone tape theory' and a key part of the game's plot. CSI: Crime Scene Investigation used this in 2005 episode "Committed", where an inmate's conversation is partially recorded on a clay
