EXERCĬTŌRĬA ACTĬO, an action granted by the edict against the exercitor navis. By the term navis was understood any vessel, whether used for the navigation of rivers, lakes, or the sea. The exercitor navis is the person to whom all the ship’s gains and earnings (obventiones et reditus) belong, whether he is the owner, or has hired the ship (per aversionem) from the owner for a time definite or indefinite.

1. Spartan Army.—In all the states of Greece, in the earliest as in later times, the general type of their military organisation was the phalanx, a body of troops in close array with a long spear as their principal weapon. It was among the Dorians, and especially among the Spartans, that this type was most rigidly adhered to. The strength of their military array consisted in the heavy-armed infantry (ὁπλίται). They attached comparatively small importance to their cavalry, which was always inferior. Indeed, the Thessalians and Boeotians were the only Greek people who distinguished themselves much for their cavalry; scarcely any other states had territories adapted for the evolutions of cavalry. The whole life of a Spartan was little else than either the preparation for or the practice of war. The result was, that in the strictness of their discipline, the precision and facility with which they performed their military evolutions, and the skill and power with which they used their weapons, the Spartans were unrivalled among the Greeks. The heavy-armed infantry of the Spartan armies was composed partly of genuine Spartan citizens, partly of Perioeci. Every Spartan citizen was liable to military service (ἔμφρουρος) from the age of twenty to the age of sixty years. They were divided into six divisions called μόραι, under the command or superintendence of a polemarch, each mora being subdivided into four λόχοι (commanded by λοχαγοί), each λόχος into two πεντηκοστύες (headed by πεντηκοστῆρες), each πεντηκοστύς into two ἐνωμοτίαι (headed by enomotarchs). The ἐνωμοτίαι were so called from the men composing them being bound together by a common oath. These were not merely divisions of troops engaged in actual military expeditions. The whole body of citizens at all times formed an army, whether they were congregated at head-quarters in Sparta, or a portion of them were detached on foreign service. The strength of a mora on actual service, of course, varied, according to circumstances. To judge by the name pentecostys, the normal number of a mora would have been 400; but 500, 600, and 900 are mentioned as the number of men in a mora on different occasions. When in the field, each mora of infantry was attended by a mora of cavalry, consisting at the most of 100 men, and commanded by an hipparmost (ἱππαρμοστής). Plutarch mentions squadrons (οὐλαμοί) of fifty, which may possibly be the same divisions. The cavalry seems merely to have been employed to protect the flanks, and but little regard was paid to it. The corps of 300 ἱππεῖς formed a sort of body-guard for the king, and consisted of the flower of the young soldiers. Though called horsemen, they fought on foot. A Spartan army, divided as above described, was drawn up in the dense array of the phalanx, the depth of which depended upon circumstances. An ἐνωμοτία sometimes made but a single file, sometimes was drawn up in three or six files (ζύγα). The enomotarch stood at the head of his file (πρωτοστάτης), or at the head of the right-hand file, if the enomotia was broken up into more than one. The last man was called οὐραγός. It was a matter of great importance that he, like the enomotarch, should be a man of strength and skill, as in certain evolutions he would have to lead the movements. The commander-in-chief, who was usually the king, had his station sometimes in the centre, more commonly on the right wing. The commands of the general were issued in the first place to the polemarchs, by these to the lochagi, by these again to the pentecosteres, by the latter to the enomotarchs, and by these last to their respective divisions. From the orderly manner in which this was done, commands were transmitted with great rapidity: every soldier, in fact, regulating the movements of the man behind him, every two being connected together as πρωτοστάτης and ἐπιστάτης. In later times the king was usually accompanied by two ephors, as controllers and advisers. These, with the polemarchs, the four Pythii, three peers (ὅμοιοι), who had to provide for the necessities of the king in war, the laphyropolae and some other officers, constituted what was called the damosia of the king. The Spartan hoplites were accompanied in the field by helots, partly in the capacity of attendants, partly to serve as light-armed troops. The number attached to an army was probably not uniform. At Plataeae each Spartan was accompanied by seven helots; but that was probably an extraordinary case. One helot in particular of those attached to each Spartan was called his θεράπων, and performed the functions of an armourer or shieldbearer. Xenophon calls them ὑπασπισταί. In extraordinary cases, helots served as hoplites, and in that case it was usual to give them their liberty. A separate troop in the Lacedaemonian army was formed by the Sciritae (Σκιρῖται), originally, no doubt, inhabitants of the district Sciritis. The arms of the phalanx consisted of the long spear and a short sword (ξυήλη). The chief part of the defensive armour was the large brazen shield, which covered the body from the shoulder to the knee, suspended, as in ancient times, by a thong round the neck, and managed by a simple handle or ring (πόρπαξ). Besides this, they had the ordinary armour of the hoplite [[Arma]]. The heavy-armed soldiers wore a scarlet uniform. The Spartan encampments were circular. Only the heavy-armed were stationed within them, the cavalry being placed to look out, and the helots being kept as much as possible outside. Preparatory to a battle the Spartan soldier dressed his hair and crowned himself as others would do for a feast. The signal for attack was given not by the trumpet, but by the music of flutes, and sometimes also of the lyre and cithara, to which the men sang the battle song (παιὰν ἐμβατήριος). The object of the music was not so much to inspirit the men, as simply to regulate the march of the phalanx. This rhythmical regularity of movement was a point to which the Spartans attached great importance.

2. Athenian Army.—In Athens, the military system was in its leading principles the same as among the Spartans, though differing in detail, and carried out with less exactness; inasmuch as when Athens became powerful, greater attention was paid to the navy. Of the four classes into which the citizens were arranged by the constitution of Solon, the citizens of the first and second served as cavalry, or as commanders of the infantry (still it need not be assumed that the ἱππεῖς never served as heavy-armed infantry), those of the third class (ζευγῖται) formed the heavy-armed infantry. The Thetes served either as light-armed troops on land, or on board the ships. The same general principles remained when the constitution was remodelled by Cleisthenes. The cavalry service continued to be compulsory on the wealthier class. Every citizen was liable to service from his eighteenth to his sixtieth year. On reaching their eighteenth year, the young citizens were formally enrolled εἰς τὴν ληξιαρχικὸν γραμματεῖον, and received a shield and spear in a public assembly of the people, binding themselves by oath to perform rightly the duties of a citizen and a soldier. During the first two years, they were only liable to service in Attica itself, chiefly as garrison soldiers in the different fortresses in the country. During this period, they were called περίπολοι. Members of the senate during the period of their office, farmers of the revenue, choreutae at the Dionysia during the festival, in later times, traders by sea also, were exempted from military service. Any one bound to serve who attempted to avoid doing so, was liable to a sentence of ἀτιμία. The resident aliens commonly served as heavy-armed soldiers, especially for the purpose of garrisoning the city. They were prohibited from serving as cavalry. Slaves were only employed as soldiers in cases of great necessity. Of the details of the Athenian military organisation, we have no distinct accounts as we have of those of Sparta. The heavy-armed troops, as was the universal practice in Greece, fought in phalanx order. They were arranged in bodies in a manner dependent on the political divisions of the citizens. The soldiers of each tribe (φυλή) formed a separate body in the army, also called a tribe, and these bodies stood in some preconcerted order. It seems that the name of one division was τάξις, and of another λόχος, but in what relations these stood to the φυλή, and to each other, we do not learn. Every hoplite was accompanied by an attendant (ὑπηρέτης) to take charge of his baggage, and carry his shield on a march. Each horseman also had a servant, called ἱπποκόμος, to attend to his horse. For the command of the army, there were chosen every year ten generals [[Strategi]], and ten taxiarchs [[Taxiarchi]], and for the cavalry, two hipparchs (ἵππαρχοι) and ten phylarchs (φύλαρχοι). Respecting the military functions of the ἄρχων πολέμαρχος, see the article Archon. The number of strategi sent with an army was not uniform. Three was a common number. Sometimes one was invested with the supreme command; at other times, they either took the command in turn (as at Marathon), or conducted their operations by common consent (as in the Sicilian expedition). The practice of paying the troops when upon service was first introduced by Pericles. The pay consisted partly of wages (μισθός), partly of provisions, or, more commonly, provision-money (σιτηρέσιον). The ordinary μισθός of a hoplite was two obols a day. The σιτηρέσιον amounted to two obols more. Hence, the life of a soldier was called, proverbially, τετρωβόλου βίος. Officers received twice as much; horsemen, three times; generals, four times as much. The horsemen received pay even in time of peace, that they might always be in readiness, and also a sum of money for their outfit (κατάστασις). As regards the military strength of the Athenians, we find 10,000 heavy-armed soldiers at Marathon, 8,000 heavy-armed, and as many light-armed at Plataeae; and at the beginning of the Peloponnesian war there were 18,000 heavy-armed ready for foreign service, and 16,000 consisting of those beyond the limits of the ordinary military age and of the metoeci, for garrison service. It was the natural result of the national character of the Athenians and their democratical constitution, that military discipline was much less stringent among them than among the Spartans, and after defeat especially it was often found extremely difficult to maintain it. The generals had some power of punishing military offences on the spot, but for the greater number of such offences a species of court-martial was held, consisting of persons who had served in the army to which the offender belonged, and presided over by the strategi. Various rewards also were held out for those who especially distinguished themselves for their courage or conduct, in the shape of chaplets, statues, &c. The Peltastae (πελτασταί), so called from the kind of shield which they wore [[Pelta]], were a class of troops of which we hear very little before the end of the Peloponnesian war. The Athenian general Iphicrates introduced some important improvements in the mode of arming them, combining as far as possible the peculiar advantages of heavy (ὁπλῖται) and light armed (ψιλοί) troops. He substituted a linen corslet for the coat of mail worn by the hoplites, and lessened the shield, while he doubled the length of the spear and sword. He even took the pains to introduce for them an improved sort of shoe, called after him Ἰφικρατίδες. This equipment proved very effective. The almost total destruction of a mora of Lacedaemonian heavy-armed troops by a body of peltastae under the command of Iphicrates was an exploit that became very famous. When the use of mercenary troops became general, Athenian citizens seldom served except as volunteers, and then in but small numbers. The employment of mercenaries led to considerable alterations in the military system of Greece. War came to be studied as an art, and Greek generals, rising above the old simple rules of warfare, became tacticians. Epaminondas was the first who adopted the method of charging in column, concentrating his attack upon one point of the hostile line, so as to throw the whole into confusion by breaking through it.

3. Macedonian Army.—Philip, king of Macedonia, made several improvements in the arms and arrangement of the phalanx. The spear (σάρισσα or σάρισα), with which the soldiers of the Macedonian phalanx were armed, was 24 feet long; but the ordinary length was 21 feet, and the lines were arranged at such distances that the spears of the fifth rank projected three feet beyond the first, so that every man in the front rank was protected by five spears. Besides the spear they carried a short sword. The shield was very large and covered nearly the whole body, so that on favourable ground an impenetrable front was presented to the enemy. The soldiers were also defended by helmets, coats of mail, and greaves; so that any thing like rapid movement was impossible. The ordinary depth of the phalanx was sixteen files, though depths of eight and of thirty-two are also mentioned. Each file of sixteen was called λόχος. Two lochi made a dilochia; two dilochiae made a τετραρχία, consisting of sixty-four men; two tetrarchies made a τάξις; two τάξεις a σύνταγμα or ξεναγία, to which were attached five supernumeraries, a herald, an ensign, a trumpeter, a servant, and an officer to bring up the rear (οὐραγός); two syntagmata formed a pentacosiarchia, two of which made a χιλιαρχία, containing 1024 men; two chiliarchies made a τέλος, and two τέλη made a phalangarchia or phalanx in the narrower sense of the word, the normal number of which would therefore be 4096. It was commanded by a polemarch or strategus; four such bodies formed the larger phalanx, the normal number of which would be 16,384. When drawn up, the two middle sections constituted what was termed the ὀμφαλός, the others being called κέρατα or wings. The phalanx soldiers in the army of Alexander amounted to 18,000, and were divided not into four, but into six divisions, each named after a Macedonian province, from which it was to derive its recruits. These bodies are oftener called τάξεις than φάλαγγες by the historians, and their leaders taxiarchs or strategi. The phalanx of Antiochus consisted of 16,000 men, and was formed into ten divisions (μέρη) of 1600 each, arranged 50 broad and 32 deep. The phalanx, of course, became all but useless, if its ranks were broken. It required, therefore, level and open ground, so that its operations were restricted to very narrow limits; and being incapable of rapid movement, it became almost helpless in the face of an active enemy, unless accompanied by a sufficient number of cavalry and light troops. The light-armed troops were arranged in files (λόχοι) eight deep. Four lochi formed a σύστασις, and then larger divisions were successively formed, each being the double of the one below it; the largest (called ἐπίταγμα), consisting of 8192 men. The cavalry (according to Aelianus), were arranged in an analogous manner, the lowest division or squadron (ἴλη), containing 64 men, and the successive larger divisions being each the double of that below it; the highest (ἐπίταγμα) containing 4096. Both Philip and Alexander attached great importance to the cavalry, which, in their armies, consisted partly of Macedonians, and partly of Thessalians. The Macedonian horsemen were the flower of the young nobles. They amounted to about 1200 in number, forming eight squadrons, and, under the name ἕταιροι, formed a sort of body-guard for the king. The Thessalian cavalry consisted chiefly of the elite of the wealthier class of the Thessalians, but included also a number of Grecian youth from other states. There was also a guard of foot soldiers (ὑπασπισταί), whom we find greatly distinguishing themselves in the campaigns of Alexander. They seem to be identical with the πεζέταιροι, of whom we find mention. They amounted to about 3000 men, arranged in six battalions (τάξεις). There was also a troop called Argyraspids, from the silver with which their shields were ornamented. They seem to have been a species of peltastae. Alexander also organised a kind of troops called διμάχαι, who were something intermediate between cavalry and infantry, being designed to fight on horseback or on foot, as circumstances required. It is in the time of Alexander the Great, that we first meet with artillery in the train of a Grecian army. His balistae and catapeltae were frequently employed with great effect, as, for instance, at the passage of the Jaxartes.

(2) Roman. General Remarks on the Legion.—The name Legio is coeval with the foundation of Rome, and denoted a body of troops, which, although subdivided into several smaller bodies, was regarded as forming an organised whole. It was not equivalent to what we call a regiment, inasmuch as it contained troops of all arms, infantry, cavalry, and, when military engines were extensively employed, artillery also; it might thus, so far, be regarded as a complete army, but on the other hand the number of soldiers in a legion was fixed within certain limits, never much exceeding 6000, and hence when war was carried on upon a large scale, a single army, under the command of one general, frequently contained two, three, or more legions, besides a large number of auxiliaries of various denominations. The legion for many centuries was composed exclusively of Roman citizens. By the ordinances of Servius Tullius those alone who were enrolled in the five classes were eligible, and one of the greatest changes introduced by Marius (B.C. 107) was the admission of all orders of citizens, including the lowest, into the ranks. Up to the year B.C. 107, no one was permitted to serve among the regular troops of the state, except those who were regarded as possessing a strong personal interest in the stability of the commonwealth; but the principle having been at this period abandoned, the privilege was extended after the close of the Social War (B.C. 87) to nearly the whole of the free population of Italy, and by the famous edict of Caracalla (or perhaps of M. Aurelius), to the whole Roman world. Long before this, however, the legions were raised chiefly in the provinces; but it does not appear that the admission of foreigners not subjects was ever practised upon a large scale until the reign of the second Claudius (A.D. 268-270), who incorporated a large body of vanquished Goths, and of Probus (A.D. 276-282), who distributed 16,000 Germans among legionary and frontier battalions. From this time forward what had originally been the leading characteristic of the legion was rapidly obliterated, so that under Diocletian, Constantine, and their successors, the best soldiers in the Roman armies were barbarians. The practice of granting pensions for long service in the shape of donations of land was first introduced upon a large scale after the Mithridatic wars. Hence, when Augustus, in compliance with the advice of Maecenas, determined to provide for the security of the distant provinces, and for tranquil submission at home by the establishment of a powerful standing army, he found the public mind in a great degree prepared for such a measure, and the distinction between soldier and civilian unknown, or at least not recognised before, became from this time forward as broadly marked as in the most pure military despotisms of ancient or modern times. The legions were originally numbered according to the order in which they were raised. As they became permanent, the same numbers remained attached to the same corps, which were moreover distinguished by various epithets of which we have early examples in the Legio Martia, and the Legio Quinta Alauda. [[Alauda].] Several legions bore the same number: thus there were four Firsts, five Seconds, and five Thirds. The total number of legions under Augustus was twenty-five, under Alexander Severus thirty-two, but during the civil wars the number was far greater.—The number of soldiers who, at different periods, were contained in a legion, does not appear to have been absolutely fixed, but to have varied within moderate limits. Under Romulus the legion contained 3000 foot soldiers. It is highly probable that some change may have been introduced by Servius Tullius, but, in so far as numbers are concerned, we have no evidence. From the expulsion of the Kings until the second year of the second Punic War, the regular number may be fixed at 4000 or 4200 infantry. From the latter period until the consulship of Marius the ordinary number may be fixed at from 5000 to 5200. For some centuries after Marius the numbers varied from 5000 to 6200, generally approaching to the higher limit. Amid all the variations with regard to the infantry, 300 horsemen formed the regular complement (justus equitatus) of the legion. When troops were raised for a service which required special arrangements, the number of horsemen was sometimes increased beyond 300. It must be observed, however, that these remarks with regard to the cavalry apply only to the period before Marius. We now proceed to consider the organisation of the legion at five different periods.

First Period. Servius Tullius. The legion of Servius is so closely connected with the Comitia Centuriata that it has already been discussed in a former article [[Comitia]], and it is only necessary to repeat here that it was a phalanx equipped in the Greek fashion, the front ranks being furnished with a complete suit of armour, their weapons being long spears, and their chief defence the round Argolic shield (clipeus).
