Factors Determining the Extent of the Sea

Lucretius, On the Nature of Things VI. 608–622

In the first place they wonder that nature does not make the sea grow larger, in view of the great flow of water into the sea, as all the rivers from all sides pour down. Add to this the passing rains and flitting storms which spatter every sea and soak every land. Add the springs of the sea itself. Yet all these will be to the whole bulk of the sea as the addition of scarcely one drop. Wherefore it is less remarkable that the great sea does not increase. But in addition the sun draws off by its heat a considerable amount. For we see the sun with its burning rays dry out clothes that were dripping wet. And we know that there are many seas extending over mighty surfaces. Therefore, however small an amount of moisture the sun may draw up in any one place, still it will, over so broad a surface, draw heavily from the sea.
