Greenwich meridian

I am the first meridian of Greenwich, which passes through the hospital of St. Thomas in the city of London, and runs in the plane of the planet of the island of Greenwich, whose east end is counted as the first degree of the east meridian, and whose west end is counted as the first degree of the west meridian. I am represented by a pillar bearing the character of the hospital, and running through the plane of the plane of the island, which is five degrees to the east of the plane of the meridian, so that I run through the five degrees of the east meridian, and through the five degrees of the west meridian. I am drawn from the hospital to the monument, which is erected on the spot where the meridian was first established, and which corresponds with the meridian of the island
