Of course aromatic materials were used in Biblical times for various medicinal, religious and ceremonial purposes but these materials would not have been essential oils, at least not by todays definition of being steam distilled products. This would have been impossible given that steam distillation had not yet even been discovered! Most people attribute the discovery of true steam distillation to a Persian scientist named Avicenna (Ibn Sina) in the 11th century. There was certainly no steam distillation over 2300 years earlier in King Tut's time. Aromatic products used during these ancient times would have been of a crude solvent extracted nature using fats and pressed oils and the like and would not have been very concentrated (not to mention that extracted products yield very different chemistry than distilled products) and therefore their use cannot really be related to how we should use the steam distilled essential oils of today.
