Another custom that served to furnish useful elements for the development of the art of medicine was that of the votive tables, hung in the temples by patients after their recovery, in sign of gratitude for having received the invoked blessings. These tables contained a brief description of the malady and of the treatment that had proved useful in dispelling it. If we reflect that dental affections are often of long duration and very tormenting, the thought naturally suggests itself that among the votive tables not a few must have referred to maladies of the teeth. The numberless cases recorded by votive tables afforded precious clinical material, which without doubt was utilized in a great measure by the priests in compiling the earliest medical writings, and, as we shall see later, Hippocrates himself stored up all the medical records existing in the celebrated temple of Cos. [Illustration: _Introduction of Ebers’ Papyrus, transcribed in Egyptian hieroglyphic characters._] CHAPTER I. DENTAL ART AMONG THE EGYPTIANS. Among the people of ancient times, the Egyptian nation was, without doubt, the one in which civilization first took its rise and had its earliest development. From the time of Menes, first King of Egypt (3892 B.C.), the inhabitants of the valley of the Nile were well advanced on the path of civilization, and under the fourth dynasty, dating from 3427 years before the Christian era, they had already attained a high degree of progress. Medical art and science in every country have always progressed in proportion to the general civilization, for the treatment of disease is one of the first and most important manifestations of civilized life. It is therefore natural that the healing art should have flourished earlier in Egypt than elsewhere, that is, in the midst of the oldest civilized people. There, as in other countries, medicine was practised for some time only by the sacerdotal caste; but not all the members of this caste were doctors and priests at one and the same time; there was a special class among them, called “pastophori,” whose mission it was to cure the sick. Our knowledge of medicine as practised among the Egyptians of old is now no longer limited to the scanty notices handed down to us by Greek and Roman writers. The researches made by students of Egyptian lore have placed original medical writings in our hands, now already partly interpreted, that permit us to form a sufficiently exact idea of the science of Medicine in ancient Egypt.
