The love of the mysterious found its greatest development in Spain in the study of divination, in omens and in auguries. In the practice of this art Spain excelled all other countries of Europe in the Middle Ages. Gaston Paris makes the following significant statement in speaking of the episode of the journey of the seven sons of Lara going to visit their uncle Ruy Velázquez, the quarrel and reconciliation:

“Tout cet épisode est fort beau et d’un caractère bien original; il n’y a rien de pareil dans notre épopée; on sait au contraire le grand rôle que jouait, dans le haut moyen âge espagnol, et surtout dans la vie des aventuriers qui faisaient la force et la terreur de la Castille, l’ inspection du vol des oiseaux; le Cid lui-même “vivait à augure.”[77]

The Spanish at this time, in spite of the intermixtures of other races, were essentially a Roman people and this was one of the characteristics of the old Roman civilization that had not been materially changed by time or religion. It is true that such practices in all cases except by means of astrology, were forbidden by law,[78] but the fact that the law was so full and explicit implies that divination and the study of omens and auguries not only existed but must have been quite common. Such customs are usually mentioned merely in passing, as in the miracle of the Host mentioned on page 118 or in such statements as the one to the effect that king Herod died according to the prognostications of a Greek augur,[79] or the simple statement that a certain person foretold that certain events would come to pass without giving any clue as to how this information was received[80]. Another indication that divining was quite common is that when Tiberius expelled from Rome all who practiced black magic the chronicler considered the event of such minor importance that he gives it only two lines:

“ ... Echo de la
cibdat de Roma todos los adeuinos et los encantadores;”[81]

Under the law in Las Siete Partidas treating of actions for which a person might be legally dishonored, is the following entry:

Como maguer el astrologo diga alguna cosa de otro por
razón de su arte, non le puede ser desmandado
por deshonra.

Pierden los homes á las vegadas algunas de sus cosas, et van á los astrólogos a rogar que caten por su arte quales son aquellos que las tienen, et los astrólogos usando de su sabiduria dicen ó señalan á algunos que las han: et en tal caso como este decimos que los que asi señalaren non pueden demandar que les fagan emienda desto asi como en manera de deshonra: et esto es porque lo que ellos dicen, fácenlo segunt su arte, et non con entención de los deshonrar. Pero como quier que non puedan demandar emienda dello como en manera de deshonra, con todo eso si el adevino fuese baratador que faga muestra de saber lo que non sabe, bien lo pueden acusar que reciba la pena que mandan las leyes del título de los adevinos et de los encantadores.”[82]

Very closely associated with the foregoing accounts, altho differing somewhat in nature, are a large number of legends mentioning wonderful signs that appear in the heavens or on the earth at certain significant moments in the life of an individual or nation. These differ from omens and auguries because they are out-of-the-ordinary happenings, while with auguries and omens proper there is nothing whatever unusual in the event itself and all depends upon the interpretation. The wonderful signs usually require interpretation, but the person seeing them, even the uninitiated, knows immediately that they have a meaning. When Octavius Caesar ascended the throne there appeared a rainbow around a clear sun, and again, three suns appeared that merged into one, signifying first, that the Roman Empire, divided into three at the death of Caesar, would become one, and second, that Christ would show the world the mystery of the Trinity[83]. More portentous still were the phenomena which appeared during the consulship of Sextus Julius Caesar and Lucius Marcus, when many signs, fire and noises occurred in the sky, blood flowed from bread as if it were meat when it was cut, real stones and earth were hailed upon the land, the earth opened and flames shot to the sky, a mountain of the color of gold descended from heaven and ascended again until it covered the sun, tame animals became wild, etc.[84] Then, as we leave Roman history and come on down to the 7th century, a sign in the form of a sword appeared in the sky and remained for 30 days, which “demostraua el sennorio que los moros auien de auer.”[85]

While usually quite distinct, the line between these marvelous signs, and omens and auguries proper, may at times become almost imperceptible; as, for instance, when queen Dido arrived in Africa she immediately prepared to build a city, and as the workmen set about digging the foundation for the walls they found the skull of a cow. This was taken to the augurs and they declared it signified that any city built there would always be one of toil and always under the power of others. They moved to another place and again began to dig, this time finding the skull of a horse, which, said the augurs, signified that a city built in that place would always be one of pride and of warriors.[86]

Incidents of this kind might conveniently be placed in either class, because, altho the event itself does not startle one, it does not take a soothsayer to tell a person of an imaginative turn of mind that a skull found under such circumstances probably has a significance.
