Medicine in ancient Rome mother's milk (or colostrum) is actually a rather effective treatment. Colostrum has been shown to prevent the growth of "Staphylococcus" bacteria, which are a known cause of several types of infection. Colostrum is about half as effective as some antibiotics prescribed to patients today. Colostrum is also effective against the bacterium chlamydia; this is the cause of a sexually transmitted disease and also can cause severe sight impairment, if not blindness. Thus, colostrum was a rather effective treatment in the ancient world – perhaps that is why it was viewed as a divine treatment. The interpretation of dreams was another
Invariant of a binary form 4"c""a" − "a""d" of degree 4. The algebra of covariants is generated by the discriminant, the form itself (degree 1, order 3), the Hessian "H" (degree 2, order 2) and a covariant "T" of degree 3 and order 3. They are related by the syzygy 4"H"="Df"-"T" of degree 6 and order 6. The algebra of invariants of a quartic form is generated by invariants "i", "j" of degrees 2, 3. This ring is naturally isomorphic to the ring of modular forms of level 1, with the two generators corresponding to the Eisenstein series "E" and "E". The algebra of covariants
