Hi I am doing some research on Tudor London specifically during the time of Henry VIII. I have found out that there was a large clock at St Pauls that rang out the hours. However I haven't found any reference to other public time devices. Also in the public usage were the daily times still refered to as Terce Sext None Vespers and Compline as in the monastic fashion or had they moved to 9 o'clock 10'clock and so on?
[Updated to add - there was a little discussion of the "o'clock" usages in this previous thread. - Lara]
