Final answer:
Gulliver sailed on a fictional ship named 'The Antelope' in Swift's 'Gulliver's Travels', which is not a historical event but a literary work.
Step-by-step explanation:
The ship that Gulliver sailed on from Bristol on May 4th, 1699, to go to Lilliput is not specified in the provided references. However, from Jonathan Swift's fictional work 'Gulliver's Travels', Lemuel Gulliver sets sail on a ship named The Antelope.
This voyage is purely fictional and is part of the satirical narrative of 'Gulliver's Travels' which explores human nature through fantastical adventures. It’s important to remember that the events described in 'Gulliver’s Travels' are not historical facts but rather elements of a literary work.
