In the Western Classical literature cloves are mentioned by Pliny the Elders' Natural History.[citation needed] Dioscorides mentions cloves in his book De materia medica.[citation needed] The Liber Pontifcalis records an endowment made by Passinopolis under Pope Sylvester I. This endowment included an Egyptian estate, its annual revenues, 150 libra (around 50 kg or 108 lb) of cloves, and other amounts of spices and papyrus.[18] Cosmas Indicopleustis in his book Topographia Christiana outlined his travels to Sri Lanka, and recounted that the Indians said that cloves, among other products, came in from unspecified places along sea trade routes.[11][citation needed]
