Amazon. The Spaniards first called this river the Orellana, in honour of their countryman who navigated it, but after hearing accounts of the fighting women on its banks they gave it the name of the fabled African tribe of warlike women who cut or burnt off the right breast in order the better to steady the bow.

Amen Corner. Old Stow tells us this lane was suddenly stopped up in his time, so that people said “Amen” on finding they had to turn back again. There may be something in this; but the greater likelihood is that it was here where the monks finished the recital of the Paternoster before they took up the Ave Maria while on their way in solemn procession to St Paul’s at the great Church festivals.
