It mostly depends upon what you mean by "computing". Computing device can simply mean that the device is programmable and capable of automated calculations. In this case, the earliest known computing device is the "castle clock",invented by Al-Jazari. It was considered the earliest programmable analog computer, dating to 1206. The castle clock was able to automatically open doors to represent that an hour in a day has passed, and it was also able to be programmed to change the amount of time it keeps track of to show that a day has passed, allowing the user to compensate for the changing lengths of day and night throughout the year.
