Let the law never be contradictory to custom: for if the custom be good, the law is worthless.
CLIMATE
Climate influences religion as regards customs and ceremonies. A legislator will not have had difficulty in making the Indians bathe in the Ganges at certain seasons of the moon; it is a great pleasure for them. He would have been stoned if he had proposed the same bath to the peoples who dwell on the banks of the Dwina near Archangel. Forbid pig to an Arab who would have leprosy if he ate of this flesh which is very bad and disgusting in his country, he will obey you joyfully. Issue the same veto to a Westphalian and he will be tempted to fight you.
Abstinence from wine is a good religious precept in Arabia where orange water, lemon water, lime water are necessary to health. Mohammed would not have forbidden wine in Switzerland perhaps, especially before going to battle.
There are customs of pure fantasy. Why did the priests of Egypt imagine circumcision? it is not for health. Cambyses who treated them as they deserved, they and their bull Apis, Cambyses' courtiers, Cambyses' soldiers, had not had their prepuces lopped, and were very well. Climate does nothing to a priest's genitals. One offered one's prepuce to Isis, probably as one presented everywhere the first fruits of the earth. It was offering the first fruits of life.
Religions have always rolled on two pivots; observance and creed: observance depends largely on climate; creed not at all. One could as easily make a dogma accepted on the equator as the polar circle. It would later be rejected equally at Batavia and in the Orkneys, while it would be maintained unguibus et rostro at Salamanca. That depends in no way on the soil and the atmosphere, but solely on opinion, that fickle queen of the world.
Certain libations of wine will be precept in a vine-growing country, and it will not occur to a legislator's mind to institute in Norway sacred mysteries which cannot be performed without wine.
It will be expressly ordered to burn incense in the parvis of a temple where beasts are slaughtered in the Deity's honour, and for the priests' supper. This butcher's shop called "temple" would be a place of abominable infection if it were not continually purified: and without the assistance of aromatics, the religion of the ancients would have caused the plague. Even the interior of the temple was decked with festoons of flowers in order to make the air sweeter.
