statues of well-off administrators and their wives, many in wood as Egypt is one of the few places in the world where the climate allows wood to survive over millennia, and many block statues. The so-called reserve heads, plain hairless heads, are especially naturalistic, though the extent to which there was real portraiture in ancient Egypt is still debated. Early tombs also contained small models of the slaves, animals, buildings and objects such as boats (and later ushabti figures) necessary for the deceased to continue his lifestyle in the afterlife. However, the great majority of wooden sculpture have been lost to decay, or probably used as fuel. Small figures of deities, or their animal personifications, are very common, and found in popular materials such as pottery. There were also large numbers of small carved objects, from figures of the gods to toys and carved utensils. Alabaster was used for expensive versions of these, though painted wood was the most common material, and was normal for the small models of animals, slaves and possessions placed in tombs to provide for the afterlife. Very strict conventions were followed while crafting statues, and specific rules governed the appearance of every Egyptian god. For example, the sky god (Horus) was to be represented with a falcon's head, the god of funeral rites (Anubis) was to be shown with a jackal's head. Artistic works were ranked according to their compliance with these conventions, and the conventions were followed so strictly that, over three thousand years, the appearance of statues changed very little. These conventions were intended to convey the timeless and non-ageing quality of the figure's ka. A common relief in ancient Egyptian sculpture was the difference between the representation of men and women. Women were often represented in an idealistic form, young and pretty, and rarely shown in an older maturity. Men were shown in either an idealistic manner or a more realistic depiction. Sculptures of men often showed men that aged, since the regeneration of ageing was a positive thing for them whereas women are shown as perpetually young. Stele A stele is an upright tablet of stone or wood, often with a curved top, painted and carved with text and pictures. Numerous examples were produced throughout Egyptian history for a variety of purposes, including funerary, votive and commemorative. Funerary stelae, attested from the early 1st Dynasty, typically bore the name and titles
