text: The clock of 1667 at Fécamp Abbey shows the time of local high tide, and the present state of the sea by means of a disc with a quarter-circle aperture which rotates with the lunar phase, revealing a green background at the syzygies (at new moon and full moon), when the tidal range is most extreme ("spring tides"), and a black background at times of smaller tidal range ("neap tides").
text: Consequently, the tides of largest range or amplitude (spring tides) occur at new moon, when the Moon and the Sun are in the same direction, and at full moon, when they are in opposite directions; the tides of smallest range (neap tides) occur at intermediate phases of the Moon.
