Re-Used Props - Various Objects
by Jörg Hillebrand and Bernd Schneider
Many props and pieces of decoration in Star Trek were later modified or even recycled without changes to represent items for a different purpose or of another civilization. Here are quite a few examples of objects such as musical instruments and tableware. Please note that every statement made here should be taken with a grain of salt. There is no need to seek for explanations. Certainly we are not supposed to watch closely enough to notice that the same items are used in distant corners of the galaxy.
The octagonal Betazoid gong, as visible and (too often!) audible in TNG: "Haven" and "Manhunt", is essentially the same as the Taresian gong in VOY: "Favorite Son". The round frame was removed already prior to its second appearance in "Manhunt".
The Ligonian gong in TNG: "Code of Honor" is later seen in "The Perfect Mate" in the Kriosian Temple of Akadar.
The transparent lyre played by the Edo man on the left later appears on Aldea in "When the Bough Breaks". The harp of the Edo man on the right later also shows up in "When the Bough Breaks", where it is played by Katie in her quarters. It seems to be based on Adam's guitar-like instrument in the TOS episode "The Way to Eden".
An even more notable instrument appears on Aldea too: the Vulcan lute.
The ivory-like sticks the Ligonians use to show approval or to applaud in TNG: "Code of Honor" are later seen again in "Frame of Mind", where an illusory Tilonian inmate plays with them.
The golden Ligonian tableware from TNG: "Code of Honor" and the Edo pitcher from "Justice" later appear on Aldea in "When the Bough Breaks".
The cups and pitcher used for the Klingon tea ceremony in TNG: "Up the Long Ladder" reappear in the DS9 episode "The Ship". In that episode, the Vorta Kilana brings food and drink to Sisko using this tableware.
A glass bottle with a characteristic "hole" from TNG: "Manhunt" appeared again many years later, in the Enterprise episode "The Communicator".
The Edo in TNG: "Justice" use characteristic glasses with a transparent blue ball at the bottom. These glasses reappear in the DS9 episode "Fascination" as decorative glasses. Alsia drinks from a similar glass in DS9: "Rivals".
A large soup bowl on Kataan in TNG: "The Inner Light" is later seen again in Pallra's home on Bajor in DS9: "Necessary Evil".
Black or white vase
Vases like this can be seen on Ligon II in TNG: "Code of Honor" (white), on the Edo homeworld in "Justice" (white) and on Angel One in the eponymous episode (black).
A metallic vase that could be seen beside the golden tableware on Aldea in TNG: "When the Bough Breaks" (see above) reappears in TNG: "Time Squared".
Kivas Fajo's jar
Among Kivas Fajo's treasures in TNG: "The Most Toys" there is also a striped jar with a handle, perhaps a teapot or a vase. Curiously this jar can be seen in Dr. Crusher's, O'Brien's and Worf's quarters in later TNG episodes. It is visible in Data's shelf in TNG: "Genesis" and even on Troi's table in ENT: "These Are The Voyages". Belated revenge? Anyhow, it seems like an intentional running joke that the item is passed around among the Enterprise crew, even 15 years after the original episode. The jar also appeared on Voyager. Another piece from Fajo's collection, the angular red vase, could be seen on K'mpec's Klingon attack cruiser in "Reunion".
Beata's pen from TNG: "Angel One" appears again many years later on the Alsaurian homeworld in VOY: "Resistance", where it is used by Caylem.
The Aldean holographic game from TNG: "When the Bough Breaks" also appears in a classroom aboard the USS Enterprise-D in "The Child".
