Frogs when they couple use a certain croaking invitation, which is commonly called ololygon; and when the male has thus enticed the female, they abide together all night. For in the water they cannot, and in the daytime they are afraid to engender upon the land, which in the night-time they do without control. At other times they croak more shrill and loud; and this is a sign of rain, and holds among the most assured prognostics of wet weather. 35. But what absurdity, dearest Neptune, would this passion of mine lead me into! How ridiculous should I appear, if trifling among sea-calves and frogs, I should omit one of the marine animals, the wisest and most beloved by the Gods! For what nightingales are to be compared with the halcyon for music? or who will presume to prefer the swallow’s love of offspring, the dove’s love of her mate, or the art and curiosity of the bees, to those virtues ascribed to the halcyon? One only island, as history tells us, received and entertained Latona when she gave birth; which island, floating before, was then made firm land. But when the halcyon brings forth, about the winter solstice, the whole ocean remains calm and undisturbed without the wrinkle of a wave. So that there is not any other creature for which man has so great an affection, seeing that for her sake for seven days and seven nights together, in the depth of winter, they sail without fear of shipwreck, and make their voyages upon the sea with greater safety than they travel upon the land. But if it be required that we should make a brief recital of her particular virtues, she is so great an example of conjugal affection, that she does not keep company with her mate for a single season, but for the whole year together, and that not for wantonness (for she never couples but with her own), but out of affection and friendship, like a truly virtuous married wife. And when her mate through age becomes infirm and not able to bear her company, she takes care of him, and feeds and carries him about in his old age, never forsaking nor leaving him alone, but taking him upon her shoulders, carries him from place to place, never abandoning him till death.
