The Shipwreck
Claude Joseph Vernet
1772
Learning to swim is now seasonable: but keep knowledge of your skill from non-swimmers in case of shipwreck.
'I have known many excellent swimmers, whereof some in the sight of the wished Land have perished by the Sea waves, and others have sunk by the weight of their fearful companions knowing their skill.'
Fynes Moryson Itinerary 1617
