To the above we shall add even another instance of ingenious discovery by the Greeks, and indeed of the most minute skilfulness; that so nothing may be wanting to our investigation of the geographical divisions of the earth, and the various countries thereof which have been pointed out; that it may be the better understood, too, what affinity, or relationship as it were, exists between one region and another, in respect to the length of their days and nights, and in which of them the shadows are of equal length, and the distance from the pole is the same. I shall therefore give these particulars as well, and shall state the divisions of the whole earth in accordance with the various sections of the heavens. The lines or segments which divide the world are many in number; by our people they are known as "circuli" or circles, by the Greeks they are called "paralleli" or parallels.

(34.) The first begins at that part of India which looks towards the south, and extends to Arabia and those who dwell upon the borders of the Red Sea. It embraces the Gedrosi, the Carmanii, the Persæ, the Elymæi, Parthyene, Aria, Susiane, Mesopotamia, Seleucia surnamed Babylonia, Arabia as far as Petra, Cœle Syria, Pelusium, the lower parts of Egypt called the Chora of Alexandria, the maritime parts of Africa, all the cities of Cyrenaica, Thapsus, Adrumetum, Clupea, Carthage, Utica, the two Hippo's, Numidia, the two Mauritanias, the Atlantic Sea, and the Pillars of Hercules. Within the meridian of this parallel, on the middle day of the equinox, the pin of the dial, usually called the gnomon, if seven feet in length, throws a shadow at mid-day no more than four feet long: the longest day and night are fourteen equinoctial hours respectively, the shortest being only ten.

The next circle or parallel begins with the western parts of India, and runs through the middle of Parthia, through Persepolis, the nearer parts of Persis, the nearer Arabia, Judæa, and the people who live near Mount Libanus, and it embraces Babylon, Idumæa, Samaria, Hierosolyma, Ascalon, Joppa, Cæsarea in Phoenicia, Ptolemais, Sidon, Tyre, Berytus, Botrys, Tripolis, Byblus, Antiochia, Laodicea, Seleucia, the maritime parts of Cilicia, the southern parts of Cyprus, Crete, Lilybæum in Sicily, and the northern parts of Africa and Numidia. In these regions, at the time of the equinox, a gnomon of thirty-five feet in length gives only a shadow twenty-four feet long; and the longest day and night are respectively fourteen equinoctial hours, and one-fifth of an hour, in length.

The third circle or parallel begins at the part of India which lies in the vicinity of Mount Imaiis, and runs through the Caspian Gates and the nearer parts of Media, Cataonia, (appadocia, Taurus, Amanus, Issus, the Passes of Cilicia, Soli, Tarsus, Cyprus, Pisidia, Side in Pamphylia, Lycaonia, Patara in Lycia, Xanthus, Caunus, Rhodes, Cos, Halicarnassus, Cnidos, Doris, Chios, Delos, the middle of the Cyclades, Gythium, Malea, Argos, Laconia, Elis, Olympia, Messenia in Peloponnesus, Syracuse, Catina, the middle of Sicily, the southern parts of Sardinia, Carteia, and Gades. A gnomon, one hundred inches in length, throws a shadow seventy-seven inches long; the length of the longest day is fourteen equinoctial hours and a half, plus one thirtieth of an hour.

Under the fourth circle or parallel lie those parts of India which are on the other side of the Imaiis, the southern parts of Cappadocia, Galatia, Mysia, Sardis, Smyrna, Sipylus, Mount Tmolus, Lydia, Caria, Ionia, Tralles, Colophon, Ephesus, Miletus, Chios, Samos, the Icarian Sea, the northern part of the Cyclades, Athens, Megara, Corinth, Sicyon, Achaia, Patræ, the Isthmus, Epirus, the northern parts of Sicily, the eastern parts of Gallia Narbonensis, and the sea-coast of Spain, from New Carthage westward. In these districts a gnomon of twenty-one feet throws a shadow of sixteen feet in length; the longest day contains fourteen equinoctial hours and two-thirds of an hour.

Under the fifth zone are included, from the entrance to the Caspian Sea, the Bactri, Iberia, Armenia, Mysia, Phrygia, the Hellespont, Troas, Tenedos, Abydos, Scepsis, Ilium, Mount Ida, Cyzicus, Lampsacus, Sinope, Amisus, Heraclea in Pontus, Paphlagonia, Lemnos, Imbros, Thasos, Cassandria, Thessaly, Macedonia, Larissa, Amphipolis, Thessalonica, Pella, Edessa, Berœa, Pharsalia, Carystus, Eubœa in Bœotia, Chalcis, Delphi, Acarnania, Ætolia, Apollonia, Brudisium, Tarentum, Thurii, Locri, Rhegium, the Lucani, Neapolis, Puteoli, the Tuscan Sea, Corsica, the Balearic Islands, and the middle of Spain. A gnomon, seven feet in length, in these countries gives a shadow of six feet, and the length of the day is fifteen equinoctial hours.

The sixth division, in which Rome is included, embraces the Caspian nations, Caucasus, the northern parts of Armenia, Apollonia on the Rhyndacus, Nicomedia, Nicæa, Chalcedon, Byzantium, Lysimachia, the Chersonnesus, the Gulf of Melas, Abdera, Samothracia, Maronea, Ænus, Bessica, Thracia, Mædica, Pæonia, the Illyrii, Dyrrhachium, Canusium, the extreme parts of Apulia, Campania, Etruria, Pisæ, Luna, Luca, Genua, Liguria, Antipolis, Massilia, Narbo, Tarraco, the middle parts of Hispania Tarraconensis, and thence through Lusitania. A gnomon of nine feet here throws a shadow eight feet long; the greatest length of the day is fifteen equinoctial hours, plus one-ninth part of an hour, or, according to Nigidius, one-fifth.

The seventh division begins on the other side of the Caspian Sea, and the line runs above Callatis, and through the Bosporus, the Borysthenes, Tomi, the back part of Thrace, the Triballi, the remainder of Illyricum, the Adriatic Sea, Aquileia, Altinum, Venetia, Vicetia, Patavium, Verona, Cremona, Ravenna, Ancona, Picenum, the Marsi, the Peligni, the Sabini, Umbria, Ariminum, Bononia, Placentia, Mediolanum, all the districts at the foot of the Apennines, and, beyond the Alps, Gallia Aquitanica, Vienna, the Pyrenæan range, and Celtiberia. A gnomon thirty-five feet in length here throws a shadow of thirty-six feet, except in some parts of Venetia, where the shadow just equals the length of the gnomon; the longest day is fifteen equinoctial hours, plus three-fifths of an hour.

Thus far we have set forth the results of observations made by the ancients. The remaining part of the earth has been divided, through the careful researches of those of more recent times, by three additional parallels. The first runs from the Tanais through the Mæotis and the country of the Sarmatæ, as far as the Borysthenes, and so through the Daci and part of Germany, and the Gallic provinces, as far as the shores of the ocean, the longest day being sixteen hours.

The second parallel runs through the country of the Hyperborei and the island of Britannia, the longest day being seventeen hours in length.

The last of all is the Scythian parallel, which runs from the Riphæan range to Thule, in which, as we have already stated,[1] the year is divided into days and nights alternately, of six months' duration. The same authors have also placed before the first parallel, which we have here given,[2] two other parallels or circles; the first running through the island of Meroë and the city of Ptolemais which was built on the Red Sea for the chase of the elephant; where the longest day is twelve hours and a half in length; and the second passing through Syene in Egypt, in which the longest day is thirteen hours in length. The same authors have also added half an hour to each of the parallels, till they come to the last.

Thus far on the Geography of the earth.
