Dammann wrote, "In the , specific religious ideas recede into the background... The influence of Islam manifests itself in African proverbs... Christian influences, on the contrary, are rare." If widely true in Africa, this is likely due to the longer presence of Islam in many parts of Africa. Reflection of Christian values is common in Amharic proverbs of Ethiopia, an area that has had a presence of Christianity for well over 1,000 years. The Islamic proverbial reproduction may also be shown in the image of some animals such as the dog. Although dog is portrayed in many European proverbs as the most faithful friend of man, it is represented in some Islamic countries as impure, dirty, vile, cowardly, ungrateful and treacherous, in addition to links to negative human superstitions such as loneliness, indifference and bad luck.
