Why this is in the register

The same HOLLIS query (https://hollis.harvard.edu/discovery/search?query=any,contains,Lucifer%20of%20Cagliari&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 returns this work only in Latin (PL 13 in the 1845 Migne volume; CSEL 14 for the critical text) and in the CCSL 8 edition of 1978. Neither of the two English Lucifer translations covers it: Beck's Brepols volume (https://hollis.harvard.edu/permalink/f/1s5nto6/99155522658703941) is described in its record as a translation of the two books 'Concerning Athanasius', and Flower's Liverpool volume prints only Moriendum esse pro Dei Filio. A separate query for 'Lucifer Cagliari Concerning Athanasius Brepols' confirms the scope of the Brepols volume. No English translation of this treatise was located.

The shortest and most programmatic of Lucifer's polemics: a case, argued from Scripture and from the example of the Maccabees, that any contact with Arians is pollution. It is the classic statement of the hard-line Latin position that Ambrose and the Nicene establishment had to work around, and it fixes the vocabulary of pollution and contagion that runs through later Latin heresiology. Without it the Lucifer who influenced fourth-century Latin rigorism is invisible in English.
