gossamer: [14] It would be pleasant to think that gossamer, originally ‘fine cobwebs’, is a descendant of an earlier goose-summer, but unfortunately there is not enough evidence to make this more than a conjecture. The theory goes as follows: mid-autumn is a time when geese for the table are plentiful (November was once known as gänsemonat ‘geese-month’ in German), and so a warm period around then might have been termed goose-summer (we now call it an Indian summer); the silken filaments of gossamer are most commonly observed floating in the air on such warm autumnal days; and so the spiders’ webs were christened with the name of the season.
