Solomon, Hebrew King of a united Israel, is an important figure within a variety of beliefs. He shows up in Jewish, Christian, and Islamic scripture, praised as a leader who valued wisdom over riches and who was dedicated to God.
Among occultists, particularly those working within an Abrahamic framework, he is similarly respected. After all:
The story of Solomon's wisdom speaks to a central point of occultism. The purpose of occultism is to gain hidden knowledge thru personal experience. It is not based on simply accepting revealed knowledge through scriptures, as interpreted by organized religion. Occultism is an attempt to learn spiritual truths directly yourself. (Occult View, "The occult significance of the historical King Solomon", March 8, 2010)Solomon is also credited in Rabbinical teachings as commanding angels and demons, and occult documents ascribed to him (but actually composed thousands of years later) discuss such techniques. It's important to note he commanded demons rather than worked with them, although that subtlety has led some conservative Christians to reject Solomon as a villain.
Recent archeological finds have brought the historical Solomon again to people's attention. For all of the attention and respect that Solomon gets, we're still not sure he was even a real guy and, if he was, when exactly he lived.
