Σύμφωνα με τα Αργοναυτικά του Ορφέα, η επιστροφή αρχίζει με την δολοφονία του Αψύρτου. Οι Αργοναύτες διέπλευσαν τον ποταμό Φάσι προς τις πηγές του στον Καύκασο, φτάνοντας στη Μαιώτιδα λίμνη. Ύστερα από περιπλάνηση 10 ημερών όταν η Αργώ έφτασε στα Ριπαία όρη, όπου βρίσκονται οι πηγές του Δούναβη, οι Αργοναύτες διέπλευσαν μέσω ενός στενού ρείθρου βγα...

This study traces and analyzes the itinerary followed by Argo and her crew, according to the unknown author of Argonautica Orphica: The voyage of the Argonauts from Iolcos to Colchis and their return following a different path, from Phasis River through central Europe to the Atlantic Ocean and then through the Mediterranean Sea. Conclusions are dra...

According to the unknown author of Argonautica Orphica, the return of the Argonauts begins with the murder of Absyrtus. The Argonauts sailed the Phasis River upstream, reaching Lake Maeotis. After ten days of wandering, Argo reached the Riphean Mountains, where the sources of Danube are, and then the Argonauts, passing through a narrow channel, mad...

A key aspect of Hippocratic medicine is the study of the structural elements of the human body, which are called by Hippocrates humors, in order to make known not only human body physiology, but also the causes of diseases. In the Hippocratic work there are several indications that human is directly linked not only with the natural environment but...

Abstract: When the atomic philosophers referred to atoms, they considered them as the pieces of matter that were not susceptible to further division. In modern physics �atoms� are not the fundamental constituents of matter. In such a case the term �atom� is inaccurate, since the basic elements of matter are the quarks and the leptons. Here are cons...

Размотрили смо Анаксименова схватања о формирању Земље и звезда, која се заснивају на акумулацији и "разређивању" првобитне супстанце, и дискутујемо неке сличне карактеристике са данашњом научном теоријом формирања звезда, посебно философово мишљење о ватреној природи звезда, које одражава теорије о производњи енергије у њиховој унутрашњости. We e...

Abstract. The Nestorian Christian monk Cosmas the ”Indicopleustes”, wrote in 6th century the Christian Topography, a work through which he attempted to create a new system of geography and the representation of the World that would fit to the information contained in the Holy Scripture. His work and life, and his model of the Universum, are conside...

In the paper is presented Anaximenes theory of air as the initial cause of nature which is transcendental. We examine Anaximenes account on the formation of Earth and stars, which is based on the accumulations and ”thinning” of the primal substance, and discuss some similar characteristics with the scientific theory of star formation, while the phi...

Empedocles not only considered the existence of the four 'classical' elements as the cause of the beginning of the world, but he also supported the view of their unication, which results in the creation of the imaginary world of the Sphere. According to Empedocles, the Universe existed in the state of the Sphere before the explicit presence of the...

GREGORY OF NISSA Summary Gregory of Nyssa (335–394) was the younger brother of Basil the Great (Basil of Caesarea) and he is considered one of the most important theologians of the Eastern Church. Gregory was born in Neocaesarea, on the Black Sea’s southern shore, around 335 AD and he must has been educated mainly in Caes...

New BVRI CCD observations of the semi-detached eclipsing binary EG Cep are presented. The observed light curves are analyzed with the Wilson-Devinney program and new geometrical and photometric elements are derived. These elements are used to compute the physical parameters of the system in order to study its evolutionary status.

Ancient Greek astronomers invented and constructed a variety of astronomical instruments for the measurement of time; among them we find sundials of different types. Nowadays, in Athens, there are seven ancient sundials of marble construction, which type differs due to the different shape of their dials’ surface. They are kept in the National Archa...

In the capital of Greece, Athens, several monuments of some astronomical significance are preserved till now.

In this paper we present the proposition of Empedocles, who considered the four elements of the other Ionian philosophers as united.And we discuss the results of new reserchers in particle physics with the view of Empedocles.

The significance of the observer in the perception of time has been pointed out by the Byzantine scholar, philosopher and physicist John Philoponus (6th century AD). According to Philoponus, the perception of time by humans depends on the measurement of the motions of the celestial bodies. Correspondingly, in the special theory of relativity humans...

Sundials were the first instruments constructed by the ancient Greek astronomers for the measurement of time. The two ancient sundials described in this work are marble ones of the cylindrical type; they are currently kept in the sculpture storage room of the National Archaeological Museum of Athens (index catalog numbers 3159 and 3220). Their gnom...

The ancient sundial described in this work is a marble one of the conical type; it is now in the National Archaeological Museum of Athens (index catalog number 3158). Characteristic parameters of this sundial, such as the angle formed between the cone’s axis and the generatrix, the geographical latitude of operation and the gnomon’s length, are cal...

A stone die of the Minoan period, discovered near Palaikastro in Crete, Greece, in 1899, was selected for this study as bearer of astronomical significance. Strong evidence is presented in favor of its use (especially of the "ray-bearing" disc on its right-hand side) as a die for the construction of a device that could determine eclipse dates dur...

The first Christian centuries in the Byzantine Empire, from the 3rd one to the 6th one, comprise a period in which the Christian religion had to consolidate its place as the dominant religion. Therefore, everything that seemed to contradict the Scriptures had to be adapted to them by any means. For this reason, since Geography did not agree in seve...

In Byzantine empire the knowledge of Geography was considered necessary for locating the Holy Land and for setting the boundaries of the dioceses. Essentially, Geography was studied by monks in the monasteries; the perception of the Earth by Byzantine geographers - especially by the monk Cosmas Indicopleustes - was to a large extent imaginary and i...

Η σημασία του παρατηρητή στην αντίληψη του χρόνου έχει επισημανθεί από τον Βυζαντινό λόγιο, φιλόσοφο και φυσικό Ιωάννη Φιλόπονο (6ος αιώνας). Σύμφωνα με τον Φιλόπονο η αντίληψη του χρόνου από τον παρατηρητή είναι συνάρτηση της μέτρησης της κίνησης των ουρανίων σωμάτων. Αντιστοίχως, στην Ειδική Θεωρία της Σχετικότητας ο παρατηρητής αντιλαμβάνεται το...

Abstract: The Iliad and the Odyssey, in addition to their supreme status as cornerstones of world literature, they are a rich source of information about the scientific and technological knowledge of ancient Greeks in both pre-Homeric and Homeric times. The two Homeric epic poems, dated in the 8th century BC, include, inter alia, a wealth of astron...

The following calendar systems, introduced in Europe from 18 th to 20 th cen-tury, which were in use in Europe for a shorter or longer period by a larger or smaller community, were reviewed and discussed: The French Revolutionary Calendar, the Theose-bic calendar invented by Th. Kairis, the Revolutionary Calendar of the Soviet Union (or 'Bolshevik...

The brightest star of the night sky, is Sirius, Alpha Canis Majoris (CMa). Due to its intense brightness, Sirius had one of the dominant positions in ancient mythology, legends and traditions. In this paper the references of the many ancient classical Greek and Roman authors and poets who wrote about Sirius are examined, and the problem of its 'red...

The notion of the infinite, with the modern meaning of the term, was first introduced by the Greek philosopher Anaximander (6 th Century BC). Anaximander introduced the apeiron (the boundless) as the beginning of everything (the first principle). According to his theory, the apeiron is undefined and ever moving. It gives birth to the contradictory...

In this paper the views related to nature, Mother-Earth and the natural environment in the ancient Greek world are discussed, from the Оrphic Hymns and the Homeric world, through the works of Hesiod and Sophocles, and the theories and works of the pre-Socratic philosophers, the Ionian School, Thales, Anaximander, Anaximenes, Heraclitus, Pythagoras...

In this article we consider the role of the three principal celestial bodies, the Earth (Gaia), the Sun (Helios) and the Moon (Selene), as well as the Sky (Ouranos) in the ancient Greek cosmogony. This is done by the analysis of antique Greek texts like Orphic Hymns and the literary remains of the writers and philosophers like Aeschylus, (Pseudo) A...

Pyramids, "Dragon Houses" ("Drakospita") and megalithic structures in gen-eral create always a special interest. We postulate that, as happens with the Drakospita of Euboea, the pyramid-like structures of Argolis (Eastern Peloponnese) were constructed by the Dryops. It is known that, in addition to Euboea and some Cyclades islands, this prehellenic...

A characteristic of the Western thought is the effort to counter Christian theology through arguments based on scientific discoveries (antirrhetic theology). Two objections can be raised against this trait: a) Modern science considers as a fact the future expansions, corrections, even total abolishment of scientific knowledge in the face of new dis...

In this work, four ancient monuments of astronomical significance found in Athens and still kept in the same city in good condition are presented. The first one is the conical sundial on the southern slope of the Acropolis. The second one is the Tower of the Winds and its vertical sundials in the Roman Forum of Athens, a small octagonal marble towe...

Astronomy is the most ancient of all natural sciences. From its roots in ancient Babylonian and Egyptian stellar observations, and through its formulation into a science from the Greek natural philosophers, it defined the measurement of time. The stellar eras and the applications of Astronomy were incorporated in temples, paintings, sculptures and...

This work explores the relation and interdependence among theology, science and social structure within the framework of a new ``Cultural Current'', which will probably prevail in the Western societies, through the study of the development of the cultural currents in the ages. The now prevailing in these societies Positivist Cultural Current suffer...

In the history of calendrical reforms the Julian calendar that prevailed for centuries was gradually replaced by the Gregorian one from 1582 onwards. After these two calendars, some other calendrical systems were introduced in Europe, none of which prevailed beyond its limited (in time and place) political environment. In this work the following su...

A very well preserved ancient water-clock exists at the Amphiaraeion, in Oropos, Greece. The Amphiaraeion, sanctuary of the mythical oracle and deified healer Amphiaraus, was active from the pre-classic period until the 5th Century A.D. In such a place the measurement of time, both day and night, was a necessity. Therefore, time was kept with both...

Sirius is the brightest star of the night sky, visible from all Greece, especially during clear winter nights. Sirius, because of his brightness had one of the dominant positions in mythology , legends and traditions of most ancient people.

In this paper we present the cosmological theories of the pre-Socratic Greek philosophers and their philosophical views for Environment.

In this paper we present the contributions of Byzantium to the Natural Sciences. Also we describe some views of Byzantine Astronomers and Scientists.

The relation between philosophy and science has passed from many phases in history and still is an interesting topic. The value of falsifiability (or refutability) in science was stressed by Popper. Here, as a paradigm, the juxtaposition of the Earth-centered view of the universe and the prevalence of the heliocentric theory is examined. A new phys...

The views of the ancient Greek pre-Socratic philosophers from Ionia opened new paths for the study of nature using human logic. Starting from the worship of the Earth as a goddess, they proceeded to examine its position in the Cosmos (Universe), proposing a spherical shape for our planet. They pioneered the unifying approach for the physical world,...

A very well preserved ancient water clock was discovered during excavations at the Amphiaraeion, in Oropos, Greece. The Amphiaraeion, a famous religious and oracle center of the deified healer Amphiaraus, was active from the pre-classic period until the replacement of the ancient religion by Christianity in the 5th Century A.D.. The foretelling was...
