It is very common to hear comparisons between the Gospels and other ancient literature. Often those texts are not actually quoted. The Documents for the Study of the Gospels is a collection of various texts that are related to the Gospels in some way. For example, there are samples of supernatural birth stories and ascension stories. These are helpful for allowing us to understand how ancient readers would have understood the Gospels. I found the editorial comments a little to generous in expressing potential pagan influence on the Gospels but overall this is a good resource for Gospel studies.
