Latin Etymology

Ad defensionem autem cerebri fuerunt necessari duo panni, qui vocantur matres cerebri. Unus est grossus, scilicet dura mater. Hic cranio supponitur, sed in medio cerebro ingrossatur, et ad maiorem fortitudinem solidatur, non tamen immediate cum craneo coniungitur, immo potius suspenditur, et huc atque illuc circa cerebri substantiam dilatatur... Secundus panniculus dicitur pia mater, quae durae matri supponitur, quae mollior est dura matre. Unde substantiam cerebri circumvolvit et per dictas cellulas ab invicem separat et discernit.
