I am currently reading a bit in Kepler's Epitome astronomiae copernicanae. While doing so I keep stumbling upon some unusual forms which seem to be genitives, but rather weird ones:
[Astronomia] est pars Physices.
How does one properly decline Physices and Optices? I take it that these are special because they are Greek words. Having a look a Allen & Greenough's did not help me a lot, however. Can anyone of you help me with this? Does anyone know of a good resource about declination of Greek words in a Latin context?[Astronomia] complectitur magnam partem Optices, quia commune cum ipsa subjectum habet, Lucem corporum coelestium & quia multas visus deceptiones circa mundi motuumque formas detegit.
Thanks in advance,
