Watson's Biblical & Theological Dictionary 
‘Αποκαλυψις , signifies revelation. It is, however, particularly applied to the Revelations which St. John had in the isle of Patmos, whither he had been banished. The testimonies in favour of the book of the Revelation being a genuine work of St. John the Evangelist are very full and satisfactory. Andrew, bishop of Caesarea in Capadocia, in the fifth century, assures us that Papias acknowledged the Revelation to be inspired. But the earliest author now extant who mentions this book is Justin Martyr, who lived about sixty years after it was written, and he ascribes it to St. John. So does Iraeneus, whose evidence is alone sufficient upon this point; for he was the disciple of Polycarp, who was the disciple of John himself; and he expressly tells us that he had the explanation of a certain passage in this book from those who had conversed with St. John the author. These two fathers are followed by Clement of Alexandria, Theophilus of Antioch, Tertullian, Origen, Cyprian, Lactantius, Jerome, Athanasius, and many other ecclesiastical writers, all of whom concur in considering the Apostle John as the author of the Revelation. Some few persons, however, doubted the genuineness of this book in the third and fourth centuries; but since that time it has been very generally acknowledged to be canonical; and, indeed, as Mr. Lowman observes, "hardly any one book has received more early, more authentic, and more satisfactory attestations." The omission of this book in some of the early catalogues of the Scriptures, was probably not owing to any suspicion concerning its authenticity or genuineness, but because its obscurity and mysteriousness were thought to render it less fit to be read publicly and generally. It is called the Revelation of John the Divine; and this appellation was first given to St. John by Eusebius, not to distinguish him from any other person of the same name, but as an honourable title, intimating that to him was more fully revealed the system of divine counsels than to any other prophet of the Christian dispensation.
St. John was banished to Patmos in the latter part of the reign of Domitian, and he returned to Ephesus immediately after the death of that emperor, which happened in the year 96; and as the Apostle states, that these visions appeared to him while he was in that island, we may consider this book as written in the year 95 or 96.
In the first chapter, St. John asserts the divine authority of the predictions which he is about to deliver; addresses himself to the churches of the Proconsular Asia; and describes the first vision, in which he is commanded to write the things then revealed to him. The second and third chapters contain seven epistles to the seven churches in Asia; namely, of Ephesus, Smyrna, Pergamus, Thyatira, Sardis, Philadelphia, and Laodicea, which relate chiefly to their then respective circumstances and situation. At the fourth chapter the prophetic visions begin, and reach to the end of the book. They contain a prediction of all the most remarkable revolutions and events in the Christian church from the time of the Apostle to the final consummation of all things. An attempt to explain these prophecies does not fall within the design of this work; and therefore those who are disposed to study this sublime and mysterious book are referred to Mede, Daubuz, Sir Isaac Newton, Lowman, Bishop Newton, Bishop Hurd, and many other excellent commentators. These learned men agree in their general principles concerning the interpretation of this book, although they differ in some particular points; and it is not to be expected that there should be a perfect coincidence of opinion in the explanation of those predictions which relate to still future times; for, as the incomparable Sir Isaac Newton observes, "God gave these and the prophecies of the Old Testament, not to gratify men's curiosity, by enabling them to foreknow things, but that after they were fulfilled they might be interpreted by the event, and his own prescience, not that of the interpreters, be then manifested thereby to the world." "To explain this book perfectly," says Bishop Newton, "is not the work of one man, or of one age; but probably it never will be clearly understood, till it is all fulfilled." It is graciously designed, that the gradual accomplishment of these predictions should afford, in every succeeding period of time, additional testimony to the divine origin of our holy religion.
American Tract Society Bible Dictionary 
Signifies revelation, but is particularly referred to the revelations which John had in the isle of Patmos, whither he was banished by Domitian. Hence it is another name for the book of Revelation. This book belongs, in its character, to the prophetical writings, and stands in intimate relation with the prophecies of the Old Testament, and more especially with the writings of the later prophets, as Ezekiel, Zechariah, and particularly Daniel, inasmuch as it is almost entirely symbolical. This circumstance has surrounded the interpretation of this book with difficulties, which no interpreter has yet been able fully to overcome. As to the author, the weight of testimony throughout all the history of the church is in favor of John, the beloved apostle. As to the time of its composition, most commentators suppose it to have been written after the destruction of Jerusalem, about A. D. 96; while others assign it an earlier date.
It is an expanded illustration of the first great promise, "The seed of the woman shall bruise the head of the serpent." Its figures and symbols are august and impressive. It is full of prophetic grandeur, and awful in its hieroglyphics and mystic symbols: seven seals opened, seven trumpets sounded, seven vials poured out; mighty antagonists and hostile powers, full of malignity against Christianity, and for a season oppressing it, but at length defeated and annihilated; the darkened heaven, tempestuous sea, and convulsed earth fighting against them, while the issue of the long combat is the universal reign of peace and truth and righteousness-the whole scene being relieved at intervals by a choral burst of praise to God the Creator, and Christ the Redeemer and Governor. Thus its general scope is intelligible to all readers, or it could not yield either hope or comfort. It is also full of Christ. It exhibits his glory as Redeemer and Governor, and describes that deep and universal homage and praise which the "Lamb that was slain" is forever receiving before the throne. Either Christ is God, or the saints and angels are guilty of idolatry.
"To explain this book perfectly," says Bishop Newton, "is not the work of one man, or of one age; probably it never will be clearly understood till it is all fulfilled."
