Nostromo (novel)

In the novel Nostromo by British author Joseph Conrad, there are two fictional countries, one of which is seceding from the other. They are called Republic of Costaguana and Western Republic of Sulaco.

On AlternateHistory.com, "Dr. Strangelove" has made pictures of the two countries' flags based on the descriptions in the novel.

In the novel, this flag is identified and described:

An enormous national flag of Costaguana, diagonal red and yellow, with two green palm trees in the middle, floated lazily at the mainmast head of the Juno.

I think I would have used a lighter colour of green for the palm trees, though; one that actually looks green. I'm also not sure where the 3:4 ratio comes from.

I found a flag mentioned in Nostromo by Joseph Conrad:

How the United States cruiser, Powhattan, was the first to salute the Occidental flag — white, with a wreath of green laurel in the middle encircling a yellow amarilla flower.

The Occidental Republic is a fictional nation in which the novel occurs.

In the novel, two flags are identified and described. Other than that, there are mentions of entities with flags:

• The "company flag" of the "Oceanic Steam Navigation Company" at the stern of a gig;
• An "Indian boy ... with the red flag of a surveying party in his hand";
• An "old flag of Cortez preserved in a glass case above the President's chair";
• The provinces again displaying "their old flags (proscribed in Guzman Bento's time)" ... "these old emblems of the war of Independence".

And there are mentions of colours of flags:

• There are "fluttering little green and white flags stuck upon each cart" of the convoy that transports the mine's gold. Though the design isn't mentioned, we do know from earlier in the text that San Tome miners would wear "white ponchos with a green stripe" and "also adopted white hats with green cord and braid", so it's tempting to imagine those flags as white with a green stripe. Then again, when the miners marched upon Sulaco, they came "green flags flying, a wild mass of men in white ponchos and green hats". Either there are two designs involved or the green must be dominant in the flags.
• The "Sulaco National Guard" have "an enormous green and yellow flag flapping in their midst", but there's nothing to suggest a design.
• Lastly there's a call for a white flag, but the meaning is no different from any real life attempt to stop a conflict, preferably before more people lose their heads.
