Monster of St Michael's church.

According to author Graham J. McKewan, in his MYSTERY ANIMALS OF BRITAIN AND IRELAND book, :

"The Tudor historian John Stowe, who was born 1525 and died in 1605, recorded a strange story told to him by his father -

'My father told me that, at St Michael's church in the Cornhill ward, London, on the night of St James, certain men were ringing the bells of St Michael's, in the loft, when there arose a tempest of thunder and lightning, and a thing of an ugly shape and sight was seen to come in at the south window, and it lighted on the north. For fear whereof, all the ringers fell down and lay as dead for a time, leaving the bells to ring and cease of their own accord. When the ringers came to themselves, they found certain stones of the north window to be razed and scrat as if they had been so much butter, printed with a lion's claw; the same stones were fastened there again, when it was repaired, and remain so to this day. I have seen them oft, and have put a feather or small stick into the hole where the claw had entered, three to four inches deep.
At the same time, certain maine Timber posts at Queen Hith were scrat and cleft from top to bottom, and the Pulpit Cross in Paul's churchyard was likewise scrat, cleft and overturned. One of the ringers lived in my youth, whom I have oft heard to verifye the same to be true, and I have oft heard my Father to report it'.
