1912, Morgan Robertson, s:The Wreck of the Titan: Or, Futility|The Wreck of the Titan: Or, Futility

A solid, pyramid-like hummock of ice, left to starboard as the steamer ascended, and which projected close alongside the upper, or boat-deck, as she fell over, had caught, in succession, every pair of davits to starboard, bending and wrenching them, smashing boats, and snapping tackles and gripes, until, as the ship cleared herself, it capped the pile of wreckage strewing the ice in front of, and around it, with the end and broken stanchions of the bridge.
