Lagado is a fictional city from the 1726 satirical novel Gulliver's Travels by Jonathan Swift.

Lagado is the capital of the nation Balnibarbi, which is ruled by a tyrannical king from a flying island called Laputa.

The author has vividly described bizarre and seemingly pointless experiments conducted there, for example - trying to change human excretion back into food and trying to extract sunbeams out of cucumbers or teaching mathematics to pupils by writing propositions on wafers and consuming them with "cephalick tincture".

[3] The author's ulterior motive on describing this place could possibly have been to point out the senseless side of science in his time.

Gulliver's guide on Balnibarbi, Lord Munodi, a former governor of Lagado, is a rare case of a practical-minded man in the kingdom who runs his estate well and productively, but is seen as an oddity by other Laputans because he has no ear for music and must endure social ostracism.
