Continuing the patristic texts from SPCK from a century ago is this short work by Novatian on the Trinity. Source is https://archive.org/details/treatiseofnovati00mooruoft . This one was much easier to convert to a pb. In one place I filled in some blank space where some letters were left out. I removed the "Index of Texts" since it was just bible passages, which Logos does better anyway.
The chief value of this text is the readable, smooth English translation. I have a few concerns that it smooths over things a bit too much, but there is value in works like this which let the fathers speak to today.
