Thoth, or Tehuti, was a highly composite deity. His birth was coeval with that of Ra. Let us enumerate his attributes before we seek to disentangle his significance. He is alluded to as the counter of the stars, the measurer and enumerator of the earth, as being twice great and thrice great lord of books, scribe of the gods, and as possessing knowledge of divine speech, in which he was 'mighty.' In general he was figured in human form with the head of an ibis, but sometimes he appears in the shape of that bird. He wears upon his head the crescent moon and disk, the Atef crown, and the crowns of the North and South. In the _Book of the Dead_ he is drawn as holding the writing reed and palette of the scribe, and as placing on his tablets the records of the deceased whose heart is being weighed before him. There is no reason to suppose that Thoth was totemic in character, as he belongs to the cosmogonic or nature deities, few or none of whom were of this type. Another form of Thoth is that of the dog-headed ape, which, it has been stated, symbolizes his powers of equilibrium. His principal seat of worship was Hermopolis, where Ra was supposed to have risen for the first time. To Thoth was ascribed the mental powers of Ra, and, indeed, the dicta of Ra seem to have come from his lips. He was the Divine Speech personified. But we are looking ahead. Let us discover his primitive significance before we enumerate the more or less complex attributes which are heaped upon him in later times. It is pretty clear that Thoth is originally a moon-god. He is called the 'great god' and 'lord of heaven.' Among primitive peoples the moon is the great regulator of the seasons. A lunar calendar is invariably in use prior to the introduction of the computation of time by solar revolution. The moon is thus the 'great measurer' of primitive life. Thus primitive peoples speak about the 'seed moon,' the 'deer moon,' the 'grain' or 'harvest moon,' and so on. Thoth, then, was a measurer because he was a moon-god, and conversely because of his lunar significance he was _the_ measurer. As Aah-Tehuti he symbolizes the new moon, as it is from the first appearance that time is measured by primitive peoples. His eye signifies the full moon in the same manner that the eye of Ra signifies the sun at mid-day. But it also symbolizes the left eye of Ra, or the cold half of the year, when the sun's rays were not so strong. It is sometimes also called the 'black eye of Horus,' the 'white eye' being the sun. This serves to illustrate how greatly the attributes of the Egyptian deities had become confused. As he was a moon-god, so he was to some extent connected with moisture, and we find him alluded to in chapter xcv of the _Book of the Dead_ as a rain and thunder god. Thoth as Soul-Recorder
