> Others have made independent calculations and arrived at a different conclusion: the calibration date would more likely fall sometime in the summer of 204 BCE, although Voulgaris countered that this doesn't explain why the winter solstice is engraved so prominently on the device. Any chance someone engraved it on the device after it was built? Alternatively, why does something engraved on the front necessarily have to be involved in the device calibration? Maybe they put that on there simply because it's a yearly important event that is related to astronomy?
