Diary of Richard Symonds is in Stewart Books.
Tuesday [12th November 1644], though a miserable wett windy day, the army moved over the playnes to Marlingsborough, where the King lay at the Lord Seymour's howse; the troopes to Fyfield, two myles distant, a place so full of a grey pibble stone of great bignes as is not usually scene; they breake them and build their howses of them and walls, laying mosse betweene, the inhabaitants calling them Saracens' stones, and in this parish, a myle and halfe in length, they lye so thick as you may goe upon them all the way. They call that place the Grey-weathers, because a far off they looke like a flock of sheepe.
