Sacred Number 7
by Estéban Trujillo de Gutiérrez
“Seven, too, was a sacred number, whose magic virtues had descended to the Semites from their Accadian predecessors. When the Chaldaean Noah escaped from the Deluge, his first act was to build an altar and to set vessels, each containing the third of an ephah, by sevens, over a bed of reeds, pine-wood and thorns.
Seven by seven had the magic knots to be tied by the witch, seven times had the body of the sick man to be anointed with the purifying oil.
As the Sabbath of rest fell on each seventh day of the week, so the planets, like the demon messengers of Anu, were seven in number, and “the god of the number seven” received peculiar honour.”
