A triad is an association of three kindred or correlated deities. In ancient Egypt, cycles of this type usually arose out of the association with the chief local god of other deities; in some instances the members were deemed to stand in the relationship of father, mother and child. Such were the Theban triad of Amen, Nut and Khons; the Memphite of Ptah, Sekhet and Nefertum; and the Osiris-Isis-Horus triad, which, n the Alexandrian form, comprised Serapis, Isis and Harpocrates.
In Babylonia, triads were derived from early conceptions of a cosmic trinity, such as Anu, Enlil and Ea representing sky, earth and water: and shin, Shamash and Ishtar, representing sun, moon and star. Early Aryan thought moved in the same direction in the Vedic triad of Agni, Indra and Surya, representing fire, wind and sun. out of this emerged the Brahman Trimurti, or three aspects, portrayed as a three-headed image in a famous sculpture at Elephanta, and comprising Brahma, the creator, Vishnu the preserver, and Siva the destroyer.
Buddhism adopted the principle in the Triratna, or three jewels, which were at first the Sangha or monastic order, portrayed as a man holding a lotus, the Buddha, and the Dharma, or sacred law.
The Triad Society of China, denoting the union of heaven, earth and man arose in the 18th century and became a powerful anti-dynastic movement. Research Triad
Brahma is the Hindu supreme god and creator of the cosmos. He is the first person of the Hindu triad, the others being Vishnu and Shiva. He is represented as a man of a red colour with four faces and generally four hands each of which holds a portion of the Vedas, in one a lustral vessel, in one a rosary, and in one a sacrificial spoon.

In Hindu mythology, Vishnu is the second god of the triad. He appears as a manifestation of the sun, and is represented as having four arms. Whenever a great physical or moral disorder affects the world he sent a portion of his essence to set it right in the form of an avatar or incarnation. Research Vishnu
Valency is the maximum combining power of a chemical element. The valency is expressed in relation to the number of hydrogen atoms with which one atom of another element can combine. For example, chlorine, bromine, and iodine combine with or can replace one atom of hydrogen, these elements being called univalent or monads. When an element such as oxygen combines with two atoms of hydrogen it is termed bivalent or dyad, when with three atoms (egnitrogen), trivalent or triad, and with four (egcarbon), quadrivalent or tetrad.
Other elements show higher valencies, the terms used being quinquivalent or pentad, sexivalent or hexad, septivalent or heptad, and octavalent or octad. Where an element such as argon does not combine with another element it is said to be non-valent. The valency of the elements has been ascertained by experiment.
Valencies are indicated in what are known as graphic symbols by bonds, eghydrogen chloride (hydrochloric acid) is shown as H-Cl. There is, however, the difficulty that some elements do not exhibit a constant valency. Phosphorus, for instance, combines with chlorine in two proportions, one containing three atoms of chlorine, and the other five, To explain this it is suggested that there are differences in the condition of the atoms, especially in their states of motion.

HMS Triad was a British Trident Class patrol type submarine of 1090 tons displacement launched and sunk during the Second World War. HMS Triad had a top speed of 15.25 knots surfaced and 9 knots submerged, carried a complement of 53 and was armed with one 4 inch dual-purpose gun; one 20 mm anti-aircraft gun; three machine-guns and about ten 21 inch torpedo tubes.

In music, an equivocal chord is a chord which can be resolved into several distinct keys. One whose intervals, being all minor thirds, do not clearly indicate its fundamental tone or root. That is the chord of the diminished triad, and the diminished seventh. Research Equivocal Chord
In music, a triad is a chord of three notes. The term triad is also applied to the common chord, consisting of a tone with its third and fifth, with or without the octave. Research Triad
