We shall begin our study with Mexico. But a few preliminary ethnographical remarks are indispensable. I spare you the catalogue of the numerous sources and documents from which a detailed knowledge of the Mexican religion may be drawn.[1] Such a list is in place in a book rather than in a lecture. I will only direct your attention to the noble collection made in 1830 by one of your own compatriots, Lord Kingsborough, under the title of "Antiquities of Mexico," a work of extreme importance, which reproduces, in facsimile or engravings, the monuments and ruins of ancient Mexico;[2] and the very remarkable work of Mr. H. H. Bancroft, "Native Races of the Pacific States of North America."[3] II. The region with which we are now to occupy ourselves comprises the space bounded on the South by the Isthmus of Panama, washed East and West by the oceans, and determined, roughly speaking, towards the North by a line starting from the head of the Gulf of California, and sweeping round to the mouths of the Mississippi with a curve that takes in Arizona and Southern Texas. In our day, this southern portion of North America is broken into two great divisions, the first and most southern of which is known collectively as Central America, and embraces the republics of Guatemala, Honduras, Nicaragua, Costa Rica, San Salvador and Panama. The great peninsula of Yucatan, which is now Mexican, formerly belonged to this group of Central American peoples. The second portion of the territory we are to study corresponds to the present republic of Mexico. I shall presently explain the sense in which it might be called the Mexican empire in the time of Fernando Cortes. For the present, let me ask you to remember that we are now about to speak, in a general and preliminary manner, of the region which pretty closely corresponds to the present Central America and Mexico. To begin with, we treat these two districts as a single whole, because the Europeans found them inhabited by a race which was divided, it is true, into several varieties, but was distinguished clearly from the Red-skins on the North, and still more from the Eskimos, and alone of the native races of North America had proved itself capable of rising by its own strength to a veritable civilization. The general physical type of the race is marked by a very brown skin, a medium stature, low brow, black coarse hair, prominent jaw, heavy lips, thick eyebrows, and a nose generally large and often hooked. The noble families as a rule had a clearer complexion. The women are thick-set and squab, but not without grace in their movements. In their youth they are sometimes very pretty, but they fade early. We must leave it to ethnological specialists to decide whether this type is not the result of previous crossings.
