Marrying Quotes - page 5
Moreover, there is another order of Essens, who agree with the rest as to their way of living, and customs, and laws, but differ from them in the point of marriage, as thinking that by not marrying they cut off the principal part of human life, which is the prospect of succession; nay, rather, that if all men should be of the same opinion, the whole race of mankind would fail. However, they try their spouses for three years; and if they find that they have their natural purgations thrice, as trials that they are likely to be fruitful, they then actually marry them. But they do not use to accompany with their wives when they are with child, as a demonstration that they do not many out of regard to pleasure, but for the sake of posterity. Now the women go into the baths with some of their garments on, as the men do with somewhat girded about them. And these are the customs of this order of Essens.
