Less ambiguously worded: knitting did not exist in Roman late antiquity. Romans produced their fabric by weaving. It’s very easy to tell the difference when looking at a fabric if someone points it out to you. Knitting was an early medieval probably Middle Eastern/North African invention. It took a while to spread.
It’s very awesome that someone was able to use a model of one of these to knit a glove, but one time I got wasted and knit with pencils. I really love imagining little Roman schoolchildren in woolen mittens and beanies, but it’s just not realistic.
