By 1288 a clock was placed in the Old Palace Yard, London, and remained there till the reign of Queen Elizabeth. In 1292 a clock was placed on Canterbury Cathedral, and in 1368 a striking clock was erected at Westminster. By 1500, clocks were used in private houses, and watches were introduced. In 1368 three Dutch clockmakers were invited to come to England to teach the business to native workers, though "Dutch clocks" and their makers were held in contempt some years later. There was a clock put into the tower of Hampton Court Palace in 1540 by a maker whose initials were "N. O.", all that posterity knows of him. It was the oldest clock in England that kept fairly good time. In 1575 George Gaver, "serjeant painter" as his title runs, had a sum of money allowed him for "painting the great dial at Hampton Court Palace, containing hours of day and night, and the course of sun and moon." In 1649 a striking part was added. By 1711 it was found that the clock had not been running as correctly as it should, owing to the fact that some careless or ignorant workman had removed some important parts of the works. After this discovery it was left neglected for many years, and finally lost its hands. It was in this condition in the first quarter of the nineteenth century, when G. P. R. James wrote a poem entitled "Old Clock Without Hands at Hampton Court." In 1835 the old works were removed, and a set of works put in which had been made in 1690 by Villiamy, for a clock in the Queen's Palace, St. James' Park. As this clock was not powerful enough to drive the astronomical works, these were put away. In 1880 this old clock was also removed, sold for old brass, and a brand-new clock substituted. It seems a pity that one of the earliest clocks known should have been destroyed. It was not till 1639 that Galileo published his discovery of the isochronous property of the pendulum, which was eight years after the incorporation of the London Clockmakers Company. Not only did this company train workers for clockmaking, but they also inspected clocks brought into England, and rejected those which they deemed unworthy. Richard Harris is said to have been the man who first connected the pendulum with clockwork movement, about 1641, and Harris's method was improved by Huyghens, so that by 1658 very trustworthy time-keepers were in use. Mr. Lockwood in his book on "Colonial Furniture," says that the first clock mentioned in the Massachusetts Colony was found in Boston in 1638, but in Lechford's note-book it is said that Joseph Stratton had of his brother in 1628 a clock and a watch. In 1640 Henry Parks, of Hartford, left a clock by will to the church. The first clock in New Haven belonged to John Davenport, who died in 1670.
