How did this happen? It was probably via astronomers searching for accurate instruments for observing the planets. They may have sought a new piece of apparatus ; a sort of disk which would rotate along with the earth. We call this an escapement. Such a device was likely invented in a Benedictine monastery in the early 1200s. There is no agreement where and when and it was probably not intended to replace existing methods of observing time. It was later that the potential for timekeeping of this regular circular motioned device was appreciated. An escapement refers to any machine which breaks up circular motion into regular ticks.
This regular movement was to produce devices which were not well suited to measuring days which were unequal. A collision with canonical time was going to come.
The earlist known clock was at Norwich Cathedral Priory - operational around 1273. This was replaced by a bigger one there in 1321-5. Some other examples were at Christchurch, Canterbury, Ely, Exeter and St Paul's London. They were all expensive for they required teams of workers with differing skills to create.The earliest remaining clocks can be found in Salisbury Cathedral (1396), Rouen (1389) and Wells (1392).

However the Church was not keen on losing control of the 24 hour reckoning of time. It implied that time was abstract and measurable rather than part of the natural order. People could start to consider allotted time and the best use of it. Early clocks were marked with "memento mori" reminding people of the shortness of life. Time could begin to be seen as part of a person's life or for others to exploit a person.Modern time reckoning was an affront to the power of the Church over time and to some even seemed to take away God's power over time.
As we all know the new method of time reckoning won and canonical hours eventually became attached to it too.
This process can be charted as well anywhere in St Albans.
St Albans
Before the 13th century our Abbey was using
so-called canonical hours : 12 during daylight and 12 at night. The intervals
between these varied according to the season. Summer time had longer daylight
and a shorter night and vice-versa. Commercial pressures sometimes led to the
hours to be more fixed lengths. For example the None - originally the 9th hour
mid-afternoon office had become mid-day or noon. Therefore the laity were
beginning to use time divided into 24 equal hours. The Church was losing its monopoly
of time.
A clock controlled by local laity could lead the working
day of the town by regular chiming every hour. The Church rang the opening and
closing of markets and the working day. There was a battle for control here.
Richard of Wallingford was one of our most learned abbots (1327-1336). He joined our monastery in 1308, studied gammar and philosophy at Oxford until 1314, ordained priest 1317 ; returned to Oxford to lecture. It was then he got into maths and astronomy. He wrote a treatise in Latin on the design and construction of astronomical instruments and a clock to ascertain time and the position of stars, sun and moon. After his return to St Albans in 1326 he became abbot in 1327 and spent much time and money on an astronomical clock. This became such a priority that King Edward III told Richard he would have been better spending money on restoring the abbey buildings (there had been the major collapse of several bauys in the nave in 1323). Richard apparently replied that his successors could fix the buildings but only he could do the clock. Alas he never saw it finished because he died early from leprosy. It was his successor, Michael de Mentmore, who completed it. It likely stood in the south transept and had bells, dials and wheels showing the course of the sun, moon and stars as well as the time . I think that Richard's clock was initially about daily monastic routine but also ensuring the Church's superiority and keeping control of time.
Richard's clock disappeared with the dissolution of the Abbey. Today you can see a full size replica made by enthusiasts here in 1995 in St Albans Cathedral. This was made possible by Richard's original notes being found in the Bodleian in 1965 and the painstaking translation work of Professor John North. The replica clock does not have hands but is designed to chime every hour.This provides the drive for showing the position of stars currently visible over St Albans.The position of the sun is shown via an engraved disc and a numbered grille indicates the current time as on a sundial. The phase and position of the moon can also be seen. A detailed booklet is available in the Cathedral by Alan Loomfield for clock and astronomical experts.

This was not the end of the matter because from 1403-1412 a clock tower was built in the market place. It survives to this day and is a popular tourist attraction, showing what a secular medieval clock tower was like and providing a great view over town and country. It was likely built as a protest by the townsfolk against the time monopoly of the Abbey. The original bell (christened Gabriel) was cast in Aldgate, London by William and Robert Buford sometime before 1418. It is believed that it sounded the angelus at 4 am and curfew at 8 or 9 pm. The curfew was last rung in 1863!The last time it rang out by being swung was for the funeral of Queen Victoria in 1901! Today it is still sounding out an F natural on the hour albeit by being struck on its side, as the oak frame that holds it is too weak to allow swinging. Back in 1412 the clock mechanism likely had no face and the poor clock keeper who lived in the tower had to strike the hours manually! It is unlikely to have been very accurate and the clock mechanism was replaced in the 18th century with hands and face. The present clock dates from 1866.
It is a fascinating building and open to the public
