This work is listed in the NCBEL as published in 1644; this appears to be a misunderstanding of the publication under this title of extracts from Wither's Campo-Musae (1643-4) and Speculum Speculativum (1660) in An Exact Collection of the Many Wonderful Prophecies Relating to the Government of England (London, 1689, 1691, 1714).
This work is listed in the NCBEL as appearing in 1657 and in Ecchoes from the Sixth Trumpet (1666).
Another apparent misunderstanding: this is listed in the NCBEL as a work of 1689, the '1646 edn apparently not extant'.
A similar case: the NCBEL lists this as a separate work published in 1657, but the lines which Wither printed under this title in Ecchoes from the Sixth Trumpet (1666) came from A Suddain Flash (1657).
Vaticinia Poetica, which appeared anonymously, was included in the Spenser Society canon but not in Wing or the NCBEL. One of the works Wither recorded as lost in 1660 was a Vaticinium Poeticum.
