King Edward the Third and his well-loved Queen Philippa came down to see the work, already famous, that was being carried out at Ely. In honour of her visit the Queen brought her robes of state, embroidered with "squirrels," first worn at her thanksgiving for the birth of the Black Prince. These robes she gave to the Prior John of Crauden, to be made into three copes and other vestments for the clergy. Whether the ancient cope still preserved at the Deanery can be identified as one of these is doubtful. It is of rich myrtle-green velvet, worked in gold thread, silk, and pearls, with plume-like flourishes that might well suggest the term "squirrels." Along its straight edge there is laid on a richly embroidered border, representing the Annunciation in the centre and saints with their emblems on either side. The design of the border indicates that it belongs to a date somewhat subsequent to 1330, the year when the Black Prince was born; but, seeing that it is quite separate from the velvet, it must have been added later, and the main portion of the vestment may actually be part of Queen Philippa's gift. But we must not suppose that the Ely builders were engaged during these twenty-six years only on the Octagon Tower and the adjacent restoration. Almost contemporary with the tower is Prior Crauden's lovely chapel, built to the south of the Minster from the designs of Alan of Walsingham, while at the same time, adjoining the north-eastern transept, there arose the glorious Lady Chapel. The foundation-stone of this wondrously elaborated edifice was laid in 1321, on Lady Day, by Alan of Walsingham himself; for it was he who, as architect, designed the building, though the actual carrying out of the work was committed to John of Wisbech, the Subsacrist of the Abbey. The funds were partly supplied by Bishop Montacute (whose premature death prevented the full completion of the design); partly by "the alms of the Faithful," or, as we should now say, by public subscription, and partly from a find of treasure-trove which is thus picturesquely described by the Abbey chronicler: "Now when the aforesaid chapel was in beginning, this Brother John had but little money in hand, or laid by, for the prosecution of so great a work. He betook himself therefore to prayer, and thereafter called his mates together, some being monks, some, likewise, seculars. And them he besought to meet at a certain hour, and help him in digging out a square trench which might serve for the foundation of the whole fabric.
