John Stow,
The Survey of London
“ When the great fen, or moor, which watereth the walls of the city on the north side, is frozen, many young men play upon the ice; some, striding as wide as they may, do slide swiftly; others make themselves seats of ice, as great as millstones; one sits down, many hand in hand do draw him, and one slipping on a sudden, all fall together; some tie bones to their feet and under their heels; and shoving themselves by a little picked staff, do slide as swiftly as a bird flieth in the air, or an arrow out of a cross-bow. ”
