“The seductive potentiality of Lull’s appeal to the principle of universal concord is revealed by the resumption of his project, two centuries later, by Nicholas of Cusa. Nicholas is famous as the figure who revived Plato during the years between the crisis of scholasticism and the beginning of the Renaissance.

Nicholas also propounded the idea of an infinitely open universe, whose centre was everywhere and whose circumference nowhere. As an infinite being, God transcended all limits and overcame every opposition.

As the diameter of a circle increased, its curvature diminished; so at its limit its circumference became a straight line of infinite length.

Likewise, in God all opposites coincide. If the universe had a centre, it would be limited by another universe. But in the universe, God is both centre and circumference. Thus the earth could not be the centre of the universe.

This was the starting point for a vision of the plurality of worlds, of a reality founded on mathematical principles, which can be submitted to continuous investigation, where the world, if not infinite in a strict sense, was at least capable of assuming an infinite number of guises.

The thought of Nicholas is rich in cosmological metaphors (or models) founded upon the image of the circle and the wheel (De docta ignorantia, II, 11), in which the names of the divine attributes (explicitly borrowed from Lull) form a circle where each supports and confirms the others (I, 21).

The influence of Lull is even more explicitly revealed when Nicholas notes that the names by which the Greeks, Latins, Germans, Turks and Saracens designate the divinity are either all in fundamental accord, or derive from the Hebrew tetragrammaton (see the sermon Dies sanctificatus).

The ideas of Lull had spread to the Veneto towards the close of the fourteenth century. Nicholas probably came into contact with them in Padua. Their diffusion was, in part, a reaction against a scholastic Aristotelianism now in crisis; yet the diffusion also reflected the feverish cultural atmosphere generated by close contacts with the East.

Just as Catalonia and Majorca had been frontier territories in contact with the Muslim and Jewish worlds at the time of Lull, so the Venetian Republic had opened itself to the world of Byzantium and of the Arab countries two centuries later. The emerging currents of Venetian humanism were inspired by a new curiosity and respect for other cultures (cf. Lohr 1988).

It was thus appropriate that in this atmosphere there should have reemerged the thought of a figure whose preaching, whose theological speculations, and whose research on universal language were all conceived with the aim of building an intellectual and religious bridge between the European West and the East.

Lull believed that true authority could not be based on a rigid unity, but rather on the tension between various centers. It was the laws of Moses, the revelations of Christ and the preaching of Mohammed that, taken together, might produce a unified result.

Lull’s doctrine acted as a mystical and philosophical stimulus and seemed an imaginative and poetic alternative to the encyclopedia of Aristotelian scholasticism, but it provided a political inspiration as well.

The works of a writer who had dared to put his doctrine into the vernacular proved congenial to humanists who, on the one hand, had begun to celebrate the dignity of their own native tongues, but, on the other hand, wondered how it was possible to establish a rational discussion which broke the boundaries of national traditions, a philosophy which could reanimate the body of encyclopedic scholasticism by injecting the leaven of exotic new doctrines, expressed in languages still entirely unknown.

In his De pace fidei, Nicholas opened a polemical dialogue with the Muslims. He asked himself Lull’s question: how might the truth of Christian revelation be demonstrated to followers of the two other monotheistic religions?

Perhaps, Nicholas mused, it was a mistake to translate the persons of the Trinity as “Father,” “Son” and “Holy Ghost.” Perhaps they should have been given more philosophical names (better understandable by other cultures).

In his ecumenical fervor, Nicholas even went so far as to propose to the Jews and the Muslims that, if they would accept the Gospels, he would see that all Christians received circumcision. It was a proposal, as he confessed at the end, whose practical realization might present certain difficulties. (De pace fidei, XVI, 60).

Nicholas retained from Lull the spirit of universal peace as well as his metaphysical vision. Yet before the thrilling potential of Nicholas’s own vision of an infinity of worlds could be translated into a new and different version of the art of combination, new ideas would have to fertilize the humanist and Renaissance world.

The rediscovery of the art of combination would have to wait for the rediscovery of Hebrew, for Christian kabbalism, for the spread of Hermeticism, and for a new and positive reassessment of magic.”

Epigenes and Berosus

“Like Aristarchus, Berosus was interested in sundials. His dial is said to have been semicircular, hollowed out of a square block, and cut under to correspond to the polar altitude. The Babylonian was also interested in astrology, for Vitruvius (Vitruvius, The Ten Books on Architecture, 9.8.1) declares that Berosus founded an astrological school in Cos, and a remark by Pliny (Natural History, 7.160) confirms that he had a knowledge of technical astrology. According to Pliny, Epigenes held that a man could not live as long as 112 years, but Berosus claimed that a man could not live more than 116.

We have here an allusion to the astrological doctrine that the number of years in a human life can never exceed the maximal possible number of degrees which is necessary for one quarter of the ecliptic to rise.

As Neugebauer has shown, Epigenes’s remark applies to the latitude of Alexandria, but Berosus is speaking of Babylon. It is just, I think, to regard Berosus as an astrologer who brought his doctrines to Cos, but there is no sign that he helped to advance the study of astronomy amongst the Greeks.

He belongs rather to the genethlialogists at Babylon, whom, Strabo reports, the geniune astronomers did not admit to their number. Yet there may still be some truth in the statement of Josephus that Berosus introduced astronomical doctrines of the Chaldaeans to the Greeks, as well as their philosophical doctrines; just as there is perhaps a sound basis for the remark of Moses of Chorene that Ptolemy II Philadelphus (in whose empire Cos lay) incited Berosus to translate Chaldaean records into Greek.

By Georgios Synkellos also the same Ptolemy, who reigned from 283 to 247 B.C., is said to have had Chaldaean works collected for his library and to have had them translated.

If Berosus was not the bringer of Chaldaean astronomical knowledge to Aristarchus, then a possible intermediary is Epigenes. This scholar, who came from Byzantium, is almost certainly a near contemporary of Aristarchus and Berosus, though various views about his date have been held.

His views are twice mentioned next to those of Berosus, once on the antiquity of Babylonian astronomical records and once on the greatest length of human life. His remark that a man could not live more than 112 years applies to the latitude of Alexandria, and shows that Epigenes had worked there.

From Seneca we learn also that he and Apollonius of Myndus had studied amongst the Chaldaeans, in Babylon itself presumably, as Epigenes’s reference to astronomical cuneiform texts–observationes siderum coctilibus laterculis inscriptas–suggests.

His statement that the astronomical records went back 720 years, not 480, looks like an attempt to correct Berosus. When we add that Epigenes believed that children could be born in the seventh month, a view also held by Strata, Aristarchus’s teacher; and find that Epigenes was, like Strata, interested in comets, the case for dating him early in the third century looks strong, if not conclusive.

But it is pointless to speculate about any ties he may have had with Aristarchus.”
