The Preston edition is a bit of a waste of time. Patrides 77 edition is still informative especially intro Peter Green’s short essay 1959 writers and their work no. 108 illumiminating interpretation. 

Religio Medici is in essence one of the first psychological self-portraits as well as a spiritual testimony. Urn-burial and Cyrus only properly understood when considered in polarised antithesis to each other.When that happens one realizes the modernity of Browne’s concept as the two 1658 Discourse have been described, as cosmic vision and paradox. but all of Browne a paradox to modern sensibilities as a scientist and Christian before the split between religion and science. Add to this his serious occult and hermetic inclinations. But certainly one of the influential of all writers, admired by Johnson, Coleridge and De Quincey, Borges, Woolf and Sebald.
