కొంతమంది రచయితలు ఈ కటకం దృశా శాస్త్రంలో వాడవడేదని మరి కొంతమంది దీనిని అలంకరణ వస్తువుగా వాడబడేవారని తెలియజేస్తున్నందున దీనిని ఆ కాలంలో దేనికి ఉపయోగించారో సరిగ్గా తెలియదు. అస్సీరియన్ శిల్పకారులు క్లిష్టమైన శిల్పాలను తయారుచేసేవారు. వాటిలో ఈ కటకం ఒకటి.<ref name="BBC News">{{cite news|url=http://news.bbc.co.uk/1/hi/sci/tech/380186.stm|title=World's oldest telescope?|last=Whitehouse|first=David|date=July 1, 1999|work=BBC News|quote=If one Italian scientist is correct then the telescope was not invented sometime in the 16th century by Dutch spectacle makers, but by ancient Assyrian astronomers nearly three thousand years earlier.

Italian scientist [[Giovanni Pettinato]] of the University of Rome has proposed that the lens was used by the [[Assyrian people|ancient Assyrians]] as part of a [[optical telescope|telescope]], and that this explains their knowledge of [[astronomy]] (see [[Babylonian astronomy]]).<ref name="BBC News" /> Experts on Assyrian [[archaeology]] are unconvinced, doubting that the optical quality of the lens is sufficient to be of much use. The ancient Assyrians saw the planet [[Saturn]] as a god surrounded by a ring of serpents, which Pettinato suggests was their interpretation of Saturn's rings as seen through a telescope.<ref>{{cite news |title=World's oldest telescope? |url=http://www.exn.ca/Stories/1999/06/29/63.asp |work=EXN Science Wire |date=June 29, 1999 |accessdate=2008-05-10 |archiveurl=https://web.archive.org/web/20070929091502/http://www.exn.ca/Stories/1999/06/29/63.asp |archivedate=Sep 29, 2007 |quote=Pettinato believes the lens was used by Assyrian astronomers as a telescope more than three thousand years ago.

The discoverer of the lens noted that he had found very small inscriptions on Assyrian artefacts which he suspected had been achieved with the aid of a lens.<ref name="layard" />

According to his book, Layard found the lens buried beneath other pieces of glass which looked like the enamel of an object, perhaps made of wood or ivory, which had disintegrated.<ref name="bm" /> The British Museum curator's notes propose that the lens could have been used "as a piece of inlay, perhaps for furniture", and that there is no evidence that the Assyrians used lenses for their optical qualities, e.g. for magnification or for starting fire.<ref name="bm" />
