T:

Titans: Gaia, Uranus, and their children: Kronos, Rhea, Oceanus, Tethys, Hyperion, Mnemosyne, Themis, Iapetus, Coeus, Crius, Phoebe, Thea, Prometheus, Epimetheus, Atlas and Metis. The Golden age of Man took place during the rule of Kronos and the Titans. The elder race, or first gods, they refused to give up power to the next generation of gods. A ten-year war ensued between the Titans and the Olympians led by Zeus, resulting in the Titans being exiled to Tartarus, a stormy pit beneath the Earth later called Hades. At the end of the Age of Heroes Zeus released the Titans, making Kronos king of the Elysian Isles to rule over the shades of the Heroes.

Translation of Light: if planet A is in aspect to planet B, and planet B is in aspect to planet C, then planet A may also be in aspect to planet C even if the orb between A and C is too wide. This is because their mutual aspect to planet B strengthens the aspect between A and C. This effect is particularly noticeable in harmonic syndromes of more than three planets.

Transit(ing): a moving planet at some time after birth, usually significant insofar as it aspects some planetary birth position; also, the crossing of the local meridian by a celestial body.

Trine: the 120° aspect; one third of the circle, denoting harmony, ease, gifts, stability and creativity; orb 6.° - 8°. Planets in trine are usually (but not necessarily) in the same element. For example, the Moon at 28° Cancer is trine (with a 4° orb) to the Sun at 2° Sagittarius, but they are not in the same element. Not conducive to change like the square; and, because of the inertia of the trine, the principal "use it or lose it" becomes relevant.

Tropical: referring to the northerly or southerly turning of the Sun twice a year at the solstices. This marks the seasonal cycle of light and dark on the Earth bringing about the 12 signs. Tropical and sidereal astrologers differ in that the former believe the signs to be 12 equal divisions of the interval between successive vernal equinoxes, and that these 12 stages in the Earth’s light and dark cycle, not the constellations from which they derived their names, are interpretively significant. Sidereal astrologers believe that it is the more fixed, non-precessing constellations that are interpretively significant.

T-Square: an opposition with a third planet square to both ends. Although similar in energy to the Grand Cross, this structure is said to lack its balance, and therefore to focus one’s attention on the "missing leg." A heavy transiting planet filling in the open end often initiates a crisis.
