Represented as a dwarf with a large head, big eyes, protruding tongue and bow legs (sometimes also shown with a crown of feathers and a bushy tail). Unusually he was normally shown face-on rather than in profile - (as such he is often found portrayed on mirrors, ointment jars and other such items). The very appearance of Bes was cause to give joy and good temper - his ugly looks were used to drive away evil spirits or bad influences, harmful reptiles, scorpions or similar type animals.
The non-Egyptian look of Bes has led to speculation as to his origins - he was often described as 'Coming from the Divine Land' - which could mean from the east, or elsewhere in Africa, Asia or perhaps Babylonian. He could also be described as the 'Lord of Pwene' - which indicates his beginnings in the mysterious land of Punt
Perhaps Bes is most identified with his role as a protector of childbirth - when problems arose during a delivery a clay dwarf was placed on the head of the mother and a spell was recited 4 times calling upon the dwarf god to help (in the spell the god is described as 'Great Dwarf' with a large head, short thighs and as a monkey in old age. Bes was also present in scenes showing royal births - something which was especially true during the Ptolemaic and Roman periods.
Images of Bes would normally be found in the home, sometimes he would be closely connected with Horus - stelae have been found which were called 'Horus on the crocodiles'; on the stela a young Horus (shown face-on) tightly holds reptiles or wild animals while he tramples on crocodiles, however this version of Horus has the face of Bes. A few lines of inscription are found on the back of the stela:
'You protect me against all the wild beasts of the desert,
all the crocodiles of the river,
all the snakes and scorpions,
all the insects that bite with their mandibles and sting with their tail,
all the kinds of reptiles that attack in their caves"
It has been suggested that these lines are a magical spell to give protection against such animals mentioned. (Source: ib205.tripod.com)
