[QUOTE]Originally posted by First of Two: [QB] The shadow the Earth casts on the Moon during an eclipse is circular. A ship appearing over the horizon will appear mast-first, suggesting it is coming up. The angle of incidence of sunlight at the same time in different locations at the same latitude is different, thus suggesting a curved surface (First proved by Erastothenes, Greek Librarian, some 500 BCE.)
