This is, in fact, a brief theological treatise on the doctrine of the Trinity, the power and nature of Christ, Paradise, angels, and men. He elaborately defines words denoting the members of the body, sin, grace, freewill, the law and the gospel, the active and contemplative life, virtues, vices, and the like.
(3) Allegoriae quaedam Sacrae Scripturae.—A spiritual interpretation of the names of Scripture characters: 129 from O. T. and 121 from N. T.; the latter being often from our Lord's parables, miracles, etc., as the ten virgins, the woman with the lost piece of money, the man who planted a vineyard, and the like. The angered king who sent his armies and destroyed those murderers and burnt up their city is interpreted of God the Father, who sent Vespasian Caesar to destroy Jerusalem. He shews an intimate acquaintance with Scripture and with the wonderful way it had then permeated the teaching and life of the church. The treatise is of intrinsic interest.
(4) Somewhat similar to the last is de Ortu et Obitu Patrum qui in Scriptura Laudibus Efferuntur; 64 chapters on O.T. characters and 21 on New, from Adam to Maccabaeus and from Zacharias to Titus. The genuineness of this treatise has been much doubted.
(5) Proomeia in Libros Vet. et Nov. Test.—Very brief introductions to the several books of O. and N.T., including Tobias, Judith, Esdras, and Maccabees, "ex quibus quidem Tobiae, Judith, et Maccabaeorum, Hebraei non recipiunt. Ecclesia tamen eosdem intra canonicas scripturas enumerat."
(6) Liber Numerorumqui in sanctis Scripturis occurrunt.—A mystical treatment of numbers from one to sixty, omitting some after twenty.
(7) Quaestiones tam de Novo quam de Veteri Testamento.—A series of 41 questions on the substance and teaching of Scripture with appropriate answers. Some are very interesting.
(8) Secretorum Expositiones Sacramentorum, seu Quaestiones in Vetus Tastamentum.—A mystical interpretation of the principal events recorded in the books of Moses, Joshua, Judges, Samuel, Kings, Ezra, Maccabees. The preface states that he has gathered the opinions of ancient ecclesiastical writers, viz. Origen, Victorinus, Ambrose, Jerome, Augustine, Fulgentius, Cassianus, and pope Gregory the Great. Gen. is treated of in 31 chapters, Ex. in 59, Lev. in 17, Num. in 42, Deut. in 22, Josh. in 18, Judg. in 9 (including 1 on Ruth), I. Kings (i.e. Sam.) in 21, II. Kings in 6, III. Kings in 8, IV. Kings in 8, Ezra in 3, Mac. in 1. The mystical method of interpretation is pursued to an excessive degree.
(9) De Fide Catholica ex Veteri et Novo Testamento contra Judaeos.—Addressed to his sister Florentina and apparently written at her request. It treats of the person of Christ from His existence in the bosom of the Father before the world was till His ascension and return to judgment; and the consequences of the Incarnation, viz. the unbelief of the Jews, the ingathering of the Gentiles, the conversion of the Jews at the end of the world, and the cessation of the Sabbath.
(10) Sententiarum Libri iii.—A kind of manual of Christian faith and practice, treating of God and His attributes. It discourses also upon the world, the origin of evil, angels, man, the soul, and senses of the flesh, Christ and the Holy Spirit, the church and heresies, the heathen nations, the law, seven rules or principles for the understanding of Scripture, the difference between the two Testaments, symbol and prayer, baptism and communion, martyrdom, the miracles wrought by the saints, Antichrist and his works, the resurrection and judgment, hell, the punishment of the wicked, and the glory of the just. Great use is made throughout of the works of Augustine and Gregory.
(11) De Ecclesiasticis Officiis treats of the services of the church, and of clerics, their rules and orders, the tonsure, the episcopal office, vicars episcopal, presbyters, deacons, sacristans and subdeacons, readers, psalmists, exorcists, acolytes, porters, monks, penitents, virgins, widows, the married, catechumens, exorcism, salt, candidates for baptism, the creed, the rule of faith, baptism, chrism, imposition of hands, and confirmation.
(12) Synonyma de lamentatione animae peccatricis.—One of the most curious of Isidore's works; a kind of soliloquy between Homo and Ratio. Homo begins by lamenting his lost and desperate condition in consequence of sin, and Ratio undertakes to direct him aright to a higher and holier condition issuing in the bliss of eternal felicity.
(13) Regula Monachorum.—This treatise led some to suppose Isidore a Benedictine monk, the only order then established in the West; but Gams thinks the proof not sufficient.
(14) Thirteen short letters follow: to bp. Leudefred of Cordova; to Braulio, to whom he speaks of giving a ring and a pall; to Helladius of Toledo on the fall of a certain bp. of Cordova; to duke Claudius, whom he congratulates on his victories; to Massona, bp. of Merida; and to archdeacon Redemptus.
(15) De Ordine Creaturarum.—This book has been doubted by some, and, though Arevalo maintains it to be genuine, he prints it in smaller type. Gams reckons it as Isidore's. It treats of faith in the Trinity, spiritual creation, the waters above the firmament, the firmament of heaven, the sun and moon, the devil and the nature of demons, the nature of waters and course of the ocean, Paradise, the nature of man after sin, the diversity of sinners and their place of punishment, purgatorial fire and the future life.
(16) De Natura Rerum Liber.—One of the most celebrated of Isidore's treatises, dedicated to king Sisebut (acc. a.d. 612), one of the best kings of Spain, whose death was universally lamented by the Goths. Isidore discourses of the days, the night, the seasons, the solstice and equinox, the world and its five zones, heaven and its name, the planets, the waters, the heavens, the nature, size, and course of the sun, the light and course of the moon, the eclipse of sun and moon, the course of the stars, the position of the seven planets, the light of the stars, falling stars, the names of the stars and whether they have any soul, thunder, lightning, the rainbow, clouds, showers, snow, hail, the nature and names of the winds, the signs of storms, pestilence, the heat, size, and saltness of the ocean, the river Nile, the names of sea and rivers, the position
