The terms or bounds devide each of the signs unequally by 5. Each term has its ruler and only the Sun and the Moon dont have any bounds/terms. They're like a little tiny space in that sign that gives a little bit of dignity to a specific planet that's not necessarily the ruler of the sign. If you have Jupiter in fall in Capricorn then it's not well placed and its topics are going to suffer, but if it's in its own terms/bounds of Capricorn, then it can do something. They're very ancient and we dont know the rationale behind them, we dont know how they got calculated, why they're like how they are, or who decided the divisions. But they're used much more by horary astrologers and it works like a clock anyway. There's no horary without them.

You can mark to see them on astro.com in the extended chart selection. I use the egyptian terms because that's the most used, especially by William Lilly, who's the biggest name in horary astrology. I recomend reading Lilly's Christian Astrology for anyone interested in astrology, even if theyre not interested in horary. Ptolemy made his own thing and I dont think anyone uses his division. And the chaldean terms, I dont know about them.

The only astrologer I've read that talks about the ascendant's terms is Firmicus Maternus, from the 4th century AD. He's a dramatic guy and most people get scared of reading his delineations because everything is described very tragically. But I think you still gain something from going to his book Mathesis, on book 5 (Liber Quintus), II - The Ascendant.

En un futuro post-apocalíptico donde los cyborgs han sustituído a los hombres y el pensamiento único se ha impuesto como modo de vida, un grupo de de insurgentes intentan salvar la vida de la "última" niña humana, símbolo de todo aquello que les fue arrebatado.

But before long another plot was organized against Commodus. It involved a former soldier named Maternus, who had committed many frightful crimes. He deserted from the army, persuading others to flee with him, and soon collected a huge mob of desperadoes. At first they attacked and plundered villages and farms, but when Maternus had amassed a sizable sum of money, he gathered an even larger band of cutthroats by offering the prospect of generous booty and a fair share of the loot. As a result, his men no longer appeared to be brigands but rather enemy troops.

They now attacked the largest cities and released all the prisoners, no matter what the reasons for their imprisonment. By promising these men their freedom, he persuaded them to join his band in gratitude for favors received. The bandits roamed over all Gaul and Spain, attacking the largest cities; a few of these they burned, but the rest they abandoned after sacking them.

When he was informed of these developments, Commodus, in a towering rage, sent threatening dispatches to the governors of the provinces involved, charging them with negligence and ordering them to raise an army to oppose the bandits. When the brigands learned that an army was being raised against them, they left the regions which they had been ravaging and slipped unnoticed, a few at a time, into Italy, by a quick but difficult route. And now Maternus was plotting for the empire, for larger stakes indeed. Since everything he had attempted had succeeded beyond his fondest hopes, he concluded that if he were to undertake something really important it was bound to succeed; having committed himself to a hazard from which it was impossible to withdraw, he would, at least, not die obscure and unknown.

But when he reflected that he did not have an army sufficiently powerful to resist Commodus on equal terms and in open opposition (for it was thought that the majority of the Roman people were still well disposed toward Commodus, and he also had the support of the Praetorian Guard), Maternus hoped to balance this inequality of forces by guile and cunning. This is the way he undertook to accomplish it.

Every year, on a set day at the beginning of spring, the Romans celebrate a festival in honor of the mother of the gods. All the valuable trappings of each deity, the imperial treasures, and marvelous objects of all kinds, both natural and man-made, are carried in procession before this goddess. Free license for every kind of revelry is granted, and each man assumes the disguise of his choice. No office is so important or so sacrosanct that permission is refused anyone to put on its distinctive uniform and join in the revelry, concealing his true identity; consequently, it is not easy to distinguish the true from the false.

This seemed to Maternus an ideal time to launch his plot undetected. By donning the uniform of a praetorian soldier and outfitting his companions in the same way, he hoped to mingle with the true praetorians and, after watching part of the parade, to attack Commodus and kill him while no one was on guard.

But the plan was betrayed when some of those who had accompanied him into the city revealed the plot. (Jealousy led them to disclose it, since they preferred to be ruled by the emperor rather than by a bandit chief.) Before he arrived at the scene of the festivities, Maternus was seized and beheaded, and his companions suffered the punishment they deserved.
