Tertullian

“ Undoubtedly, when the soul, by the power of death, is released from its concretion with the flesh, it is by the very release cleansed and purified: it is, moreover, certain that it escapes from the veil of the flesh into open space, to its clear, and pure, and intrinsic light; and then finds itself enjoying its enfranchisement from matter, and by virtue of its liberty it recovers its divinity, as one who awakes out of sleep passes from images to verities. ”

“ Thus every rapid death—such as a decapitation, or a breaking of the neck, [1] which opens at once a vast outlet for the soul; or a sudden ruin, which at a stroke crushes every vital action, like that inner ruin apoplexy—retards not the soul’s escape, nor painfully separates its departure into successive moments. Where, however, the death is a lingering one, the soul abandons its position in the way in which it is itself abandoned. ”

“ Inasmuch, then, as these parts of the body are severally devastated by an injury proper to each of them, even to the very last ruin and annulling of the vital powers—in other words, of the ends, the sites, and the functions of nature—it must needs come to pass, amidst the gradual decay of its instruments, domiciles, and spaces, that the soul also itself, being driven to abandon each successive part, assumes the appearance of being lessened to nothing; in some such manner as a charioteer is assumed to have himself failed, when his horses, through fatigue, withdraw from him their energies. ”
