P. S.--I should like to inquire, through your publication, if any one can give me the family of Mr. Claiborne; and any facts in his history not stated in our works? * * * * * ANCIENT CLOCK, AND ODEVAERE'S HISTORY OF IT. As a portion of the history of the magnificent clock, which came into my possession last year, is connected with Holland, I think it probable that I may, through the means of "N. & Q." and the _Navorscher_, be able to obtain the information respecting it which I desire. I shall therefore be very much obliged if you will give this communication a place. It will be necessary to give a brief description of the clock, so as to enable parties on the other side of the water to recognise and identify it. The clock, which is of copper richly gilt, and elaborately engraved, stands about four feet high, independent of the pedestal. It is of architectural design, and is divided into three stories, having detached columns at each corner. The two lower stories contain the dials in the front. The upper story exhibits the groups of moving silver figures, which strike the quarters, hours, and move in procession whilst a tune is played by a chime of bells. The whole is surmounted by a dome, on which is placed a silver cock, which flaps his wings and crows when the clock strikes. It was made by Isaac Hahrecht (the artist who made the great clock in the cathedral at Strasburg), according to the inscription on it, in the year 1589: and is evidently a model of that celebrated work condensed into a single tower, since it performs all the feats of that clock. Its reputed history, as given in a printed account of it, is, that it was made for Pope Sixtus V., and was for more than two hundred years in the possession of the Court of Rome. It afterwards came into the possession of William I., King of the Netherlands, who authorised Odevaere the antiquary, now deceased, to investigate everything concerning it, and to give a description of it. What I should wish to know is, who was this Odevaere, and where is his description of it to be found? With regard to the history of the clock, I should wish to know the authority for the statement of its having been made for the Pope, when and how it came to leave the Vatican; how it became the property of the King of Holland; when and why it ceased to belong to the crown of Holland; and under what circumstances it came over to this country, where it was exhibited in 1850? If any of the readers of "N. & Q.," or the _Navorscher_, can give me any information respecting it, I shall feel greatly obliged. OCTAVIUS MORGAN. 9.
