'We, the five representatives in our chamber, have decided that conjugial love originated with the most ancient people of the golden age, and from the creation of Adam and his wife among them. This is the origin of marriage, and together with marriage of conjugial love. As regards the strength or potency of conjugial love, we see no other source for it than the climate or situation with reference to the sun, and as a result the heat experienced on earth. We have arrived at this opinion, not from any empty notions we have thought up, but from clear observations we have made; for instance, by studying the peoples living in the tropical zone, where the heat of the day is almost burning, and peoples living nearer to or further away from that zone. We also deduce this from the way the heat of the sun works together with vital heat in earth-bound animals and in the birds of the heavens, when they breed in springtime. Moreover, is conjugial love anything but heat, which with the additional help of the sun becomes strength or potency?' This was signed H, the initial of the [Spanish] kingdom from which they came.
