"The Green Meadow" is a short story by H. P. Lovecraft and Winifred V. Jackson written in 1918/1919 and published in the spring 1927 issue of The Vagrant.
[1] As in their other collaboration, "The Crawling Chaos", both authors used pseudonyms — the tale was published as by "Elizabeth Neville Berkeley" (Jackson) and "Lewis Theobald, Jun."
Lovecraft wrote the entire text but Jackson is credited since it was based on a dream she had experienced.
Within the meteor is a small notebook, made of some indestructible material and written in classical Greek.
The notebook is the first-person account of a man trapped on a small, disintegrating island who seems threatened by shadowy forces and ultimately discovers Stethelos, a city from Lovecraft's Dream Cycle Mythos.
