Philosophy
Eastern tradition
In traditional Chinese 永 (yǒng 'eternity') exists in the 論語 (Analects).
Western tradition
The concept of eternity formed in ancient philosophy was specifically from within the Platonic tradition. During the Classical period (8th-7th century BC - 473/529 AD) Plato (c. 428–423 BC - 348/347 BC) described time as a moving image of eternity (in Timaeus 37 D) using the word: αἰών. Plato stated the kosmos was ἁγἡρων (ageless) in Timaeus 33a, in 37e6–38a6 the eternal forms are contrasted with the temporality of the world. Aristotle (384–322 BC) stated οὐρανοῦ was eternal (in Book I of Περὶ οὐρανοῦ) and an eternal world (in Physics).
The ancient Greek word for everlastingness was ἀίδιος (aidios) as exists via Plotinus, who also used the word aoin (eternity), in Ennead III.7.
Thomas Hobbes was re-stating the sense of the definition of Boethius when published 1662, as a response to John Wallis, he wrote that he considered that "eternity is a permanent now".

Religion
Eternity as infinite duration is an important concept in many lives and religions. God or gods are often said to endure eternally, or exist for all time, forever, without beginning or end. Religious views of an afterlife may speak of it in terms of eternity or eternal life.
Abrahamic religions
In Genesis 21:33 of the Old Testament El-Olam is God-Eternal.
Jesus In the Gospels explicitly threatens the wicked with an eternal punishment. In the context of Revelation 14: 9-11 of the Bible, the book Revelation describes how smoke from application of burning sulphur onto those who worship the beast will transit upwardly forever. The position onto which sinners are condemned for all time into hell, if the souls are punished in a conscious state of existence, is known as traditionalism, and annihilationism if the punishment on arrival in the infernal dominion is that their consciousness is then annulled-extincted. Thomas Aquinas (c. 1225 – 1274) believed in an eternal God, without either a beginning or end; the concept of eternity is of divine simplicity, thus incapable of being defined or fully understood by humankind. Christian theologians may regard immutability, like the eternal Platonic forms, as essential to eternity.
In the Islamic context, while azal indicates eternity at the beginning of known time and abad at the end; sarmad indicates all (both) aspects, this latter as an adjectival form is in surah 28 parts 71 and 72 of the Qur'an. In Islamic culture the eternity of the universe was a subject in the writings of Abu Ali ibn Sīna (died 1037), Abu Hamid al-Ghazali, Abu Walid Muhammad Ibn Rushd.
Egyptian
Ancient Egyptian eternity terms were neheh, for cyclical time, and djet, for linear. Rameses III (c.1187-1156 B.C.E.) funerary temple was: 'United-with -Eternity'.
Greco-Roman
Mythic Iliadical ἀθάνατος (athanatos) is the immortal.
The ancient greek word for everlasting, and/or eternal, exists in the Orphica Hymni.
The timelessness in divinity of classical period Augustine (354–430 AD), as exists in Book XI of the Confessions, and Boethius (c. 480–524), in Book V of the Consolation of Philosophy were adopted as the reality of the subject for later thinkers in the western tradition of philosophy. Boethius stated eternity was: interminabilis vitae tota simul et perfecta possessio, which is translated as "simultaneously full and perfect possession of interminable life". and nunc permanens, which in English is a: permanent now.
Vedic
Within the Vedic Rigveda, Aditi, as a goddess, is eternal.
Images
Graphic art
Some of the works of MC Escher were explorations of the idea of eternity.
Symbolism
Eternity is often symbolized by the endless snake, swallowing its own tail, the ouroboros. The circle, band, or ring is also commonly used as a symbol for eternity, as is the mathematical symbol of infinity,
∞
{\displaystyle \infty }
. Symbolically, these are reminders that eternity has no beginning or end.
