The technology was never lost in the case of the crossbows. Their relative usage dropped during the tang but it was back up by the song and ming. The qing even used repeating crossbows in the opium wars. One is in a photo of the aftermath of the battle of the taku forts. I wouldnt say rome lost interest in that kind of technology either as cicero references at least 2 more advanced orreries than the antikythera mechanism. Greece had a long tradition of this kinda gear work. By the time of eastern rome they basically truncated the machines to be more portable and reproducible. The byzantine sundial calendars were produced in quite a number which is why we see islamic scholars writing technical treastise' about them and making their own capable versions.
