How incubation sleep was carried into the Christian Church, its association with St.Cosmas and St.Damian and other saints, its practice throughout the Middle Ages, and its continuation to our own time may be read in the careful study of the subject made by Miss Hamilton (now Mrs.Dickens).( 18) There are still in parts of Greece and in Asia Minor shrines at which incubation is practiced regularly, and if one may judge from the reports, with as great success as in Epidaurus.

At one place in Britain, Christchurch in Monmouthshire, incubation was carried on till the early part of the nineteenth century.

Now the profession has come back to the study of dreams,( 19) and there are professors as ready to give suggestive interpretations to them, as in the days of Aristides.

As usual, Aristotle seems to have said the last word on the subject: "Even scientific physicians tell us that one should pay diligent attention to dreams, and to hold this view is reasonable also for those who are not practitioners but speculative philosophers,"(20) but it is asking too much to think that the Deity would trouble to send dreams to very simple people and to animals, if they were designed in any way to reveal the future.
In its struggle with Christianity, Paganism made its last stand in the temples of Asklepios.

The miraculous healing of the saints superseded the cures of the heathen god, and it was wise to adopt the useful practice of his temple.
