DRAFT 11 Introduction Navigation: The term stems from the 1530s, from Latin navigationem (nom. navigatio), from navigatus, pp. of navigare "to sail, sail over, go by sea, steer a ship," from navis "ship" and the root of agere "to drive" DRAFT 12 6 20/09/2018 Introduction Navigation: • Navigation is the process carried out autonomously by a mobile in order to govern its transfer between a pair of pre-set points: the origin and the destination From the Cambridge Dictionary: • “the act of directing a ship, aircraft, etc. from one place to another, or thescience of finding a way from one place to another” DRAFT 13 Introduction Navigation: • Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. – The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. • All navigational techniques involve locating the navigator's position compared to known locations or patterns. • Navigation, in a broader sense, can refer to any skill or study that involves the determination of position (positioning) and direction. DRAFT 14 7 20/09/2018 Introduction Navigation is composed by: • Positioning: it is intended to acquire information on the position of the mobile • Guidance: it is based on the analysis of the information obtained by the positioning and through decision-making and executive acts. it is the task of ensuring that the motion takes place in accordance with the requirements. DRAFT 15 Introduction • As defined by the Federal Standard 1037C, titled “Telecommunications: Glossary of Telecommunication TermsFS-1037C”, radiodetermination is «the determination of the position, velocity or other characteristics of an object, or the obtaining of information relating to these parameters, by means of the propagation properties of radio waves.» • There are two main fields to radiodetermination: – radiolocation, which is mainly passive – radionavigation, which is mainly active. DRAFT 16 8 20/09/2018 Introduction • Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth. • The basic principles are measurements from/to electric beacons, especially: – directions, e.g. by bearing, radio phases or interferometry; – distances, e.g. ranging by measurement of travel times; – partly also velocity, e.g. by means of radio Doppler shift. DRAFT 17 Introduction • Radiolocating is the process of finding the location of something through the use of radio waves. – It generally refers to passive uses, particularly radar—as well as detecting buried cables, water mains, and other public utilities. – It is similar to radionavigation, but radiolocation usually refers to passively finding a distant object rather than actively one's own position. DRAFT 18 9 20/09/2018 Introduction • In respect of the nature of navigation autonomy, must be noted that in radionavigation the acquisition and processing of the data is usually carried out on board by the mobile, obviously equipped with suitable radio receivers. DRAFT 19 History of Navigation • The first record of boats large enough to carry goods for trade is around 3500 B.C. and this would mark the birth of the art of navigation • The history of navigation starts with the history of seamanship. DRAFT 20 10 20/09/2018 History of Navigation • A few people have – the Norse, excelled as seafarers, – the ancient Bengalis, prominent among them – the Chinese, the: – the Venetians, – Austronesians, their – the Genoese, descendants the Malays, – Micronesians, and the Hanseatic Germans, Polynesians, – the Portuguese, – the Harappans, – the Spanish, – the Phoenicians, – the English, – the ancient Greeks, – the French, – the Romans, – the Dutch and – the Arabs, – the Danes. – the ancient Tamils, DRAFT 21 History of Navigation • Mediterranean – Sailors navigating in the Mediterranean made use of several techniques to determine their location, including staying in sight of land and understanding of the winds and their tendencies. – Minoans of Crete are an example of an early Western civilization that used celestial navigation. • The Minoans made sea voyages to the island of Thera and to Egypt. Both of these trips would have taken more than a day’s sail for the Minoans and would have left them traveling by night across open water. • Here the sailors would use the locations of particular stars, especially those of the constellation Ursa Major, to orient the ship in the correct direction. – Written records of navigation using stars, or celestial navigation, go back to Homer’s Odyssey where Calypso tells Odysseus to keep the Bear (Ursa Major) on his left hand side and at the same time to observe the position of the Pleiades, the late-setting Boötes and the Orion as he sailed eastward from her island Ogygia traversing the Ocean. – The Greek poet Aratus wrote in his Phainomena in the third century BC detailed positions of the constellations. • The pole stars were used to navigate because they did not disappear below the horizon and could be seen consistently throughout the night DRAFT 22 11 20/09/2018 History of Navigation • Mediterranean – By the third century BC the Greeks had begun to use the Little Bear, Ursa Minor, to navigate. – To navigate along a degree of latitude a sailor would have needed to find a circumpolar star above that degree in the sky. For example, Apollonius would have used β Draconis to navigate as he traveled west from the mouth of the Alpheus River to Syracuse. – The voyage of the Greek navigator Pytheas of Massalia is a particularly notable example of a very long, early voyage. • Pytheas ventured from Greece through the strait of Gibraltar to Western Europe and the British Isles. • Pytheas is the first known person to describe the Midnight Sun, polar ice, Germanic tribes and possibly Stonehenge. DRAFT 23 History of Navigation • Mediterranean – Nearchos’s celebrated voyage from India to Susa after Alexander's expedition in India is preserved in Arrian's account, the Indica. – Greek navigator Eudoxus of Cyzicus explored the Arabian Sea for Ptolemy VIII, king of the Hellenistic Ptolemaic dynasty in Egypt. – According to Poseidonius, later reported in Strabo's Geography, the monsoon wind system of the Indian Ocean was first sailed by Eudoxus of Cyzicus in 118 or 116 BC. – Nautical charts and textual descriptions known as sailing directions have been in use in one form or another since the sixth century BC. – Nautical charts using stereographic and orthographic projections date back to the second century BC – In 1900, the Antikythera mechanism was recovered from Antikythera wreck. This mechanism was built around 1st century BC. DRAFT 24 12 20/09/2018 History of Navigation • Phoenicia and Carthage – The Phoenicians and their successors, the Carthaginians, were particularly adept sailors and learned to voyage further and further away from the coast in order to reach destinations faster. – One tool that helped them was the sounding weight. • This tool was bell shaped, made from stone or lead, with tallow inside attached to a very long rope.

Doddiella kiefferi Priesner, 1951 (Hymenoptera, Platygastroidea) is here redescribed and illustrated to facilitate its identification. This is the first record of the peculiar genusDoddiella Kieffer, 1913 from Iran. The specimens were collected by Malaise traps from Fars province in southern Iran during 2012 and 2013. Iran is the north–eastern limit in the distribution of this species. Key Words: parasitoids, scelionid wasps, Malaise trap, Iran INTRODUCTION Platygastroidea in Iran is very poorly known. The majority of reports of the Scelionidae in Iran are related to the genus Trissolcus Ashmead (e.g. Radjabi & Amir Nazari, 1989; Radjabi, 2001; Hashemi Rad et al., 2002; Iranipour & Johnson, 2010) that are the best–known egg parasitoids of some pests on agricultural crops in Iran. No comprehensive study has been done on these beneficial insects in this region so far. More than a century ago Kieffer (1913) established the genus Doddiella in honor of the reputable entomologist A. P. Dodd. This genus was created as monotypic for its type species D. nigriceps Kieffer, 1913, collected from Ghana, Côte d’Or, Aburi.

  • Ctesias and the Importance of His Writings Revisited
    ELECTRUM * Vol. 19 (2012): 9–40 doi:10.4467/20843909EL.12.001.0742 CTESIAS AND THE IMPORTANCE OF HIS WRITINGS REVISITED Eran Almagor Abstract: Following the recent attempts to rehabilitate the reputation of Ctesias and the informa- tion given in his works, this paper proposes to understand certain of the seemingly fanciful details that were associated with the physician and his writings. It tries to shed some light on several uncertainties connected with Ctesias (i.e., his sojourn in Persia) and the Persica (i.e., date, original style and sources of imagery). It argues that the pedestrian lists included in the work might have been later interpolations and that the minor works circulating under Ctesias’ name might have been either sections of the Persica that were taken out to be presented as stand-alone volumes or else falsely attributed to him. The paper addresses the Indica and puts forward several pos- sibilities concerning its relation with the Persica. The infl uence of Ctesias on the author Deinon is examined, and in the appendix the impact of the Persica on Xenophon’s Anabasis is analyzed. Keywords: Ctesias, Persica, Indica, Artaxerxes II, Xenophon, Anabasis, Greek Historiography, Photius, Plutarch, Deinon. From Cnidos comes one of the more controversial and infl uential authors of Classical literature, namely Ctesias, a physician and a historian (probably fl oruit 401–392 BCE).1 Ctesias seems not only to have been one of the fi rst prose writers to dwell on his own personal experiences (in this case, at the court of the Great King Artaxerxes II), in what might be considered tantamount to a proto-autobiography,2 but also to have developed a unique genre of historical writing, following Herodotus yet going beyond his model, in creating works situated between fact and fi ction.3 On the one hand, Ctesias seems to 1 For a bibliography on Ctesias and his Persica, see the references in Alonso-Núñez (1996); Lenfant (2004); Wiesehöfer/Lanfranchi/Rollinger (2011).

The deeds of valor are truly awe-inspiring to those who take them at face value. Alexander is seen as a man who broke the mold. Libraries have been devoted to the study of Alexander. However, over the past sixty years scholars have become divided about their understanding of such a figure.
