I want to know the answer to the following question:
What kind of clocks did the Romans use?
All the background I'm provided with is that "For example, Roman water clocks had different scales for different months of the year: at Rome's latitude the third hour from sunrise, hora tertia, started by modern standards at 09:02 solar time and lasted 44 minutes at the winter solstice, but at the summer solstice it started at 06:58 and lasted 75 minutes.". Is that enough to answer the question?
