Before an Iranian archaeologist wants to study a historical sample, it must be determined what information is available in ancient Persian texts about that sample .The first step in identifying and obtaining this information is to understand the vocabularies and words relevant to that science. But sometimes words from the Persian language are outdated and alternatives from another languages are nowadays designated for that word, which are well known and used in scientific societies and Their Persian form is unknown, so the obscurity of today's obsolete equivalents makes some of the information relevant to it still ambiguous in interpreting ancient texts and remains unknown. by finding the ancient name of the words and their equivalence with the well-known words of today, valuable information can be obtain in a wide range of studies. Khomāhan is one of these ancient and obsolete Persian words that has been defined only in the historical books of medicine and minerals, dictionaries and in Persian poems and these definitions only emphasizes that it is an iron ore. In these books two types of male and female are mentioned for it. It is said that female khomāhan is a reddish- black stone that, when sinking in water, red color will be appeared and It has been used as a red pigment like a vermillion, and the male khoamāhan is a black stone and when sinking it in water yellow color will be appeared, it has been used as a yellow pigment like an orpiment. In Persian poetry also is mentioned about magnetic or black khomāhan. Black khomāhan is also a kind of a very black colored stone and is considered to be the best kind of khomāhan. Thus, the word khomāhan is referred to three stone but it is not known precisely which word or equivalent is known today. In this regard, female khomāhan that has been used in ancient medicine in Iran is found from perfumery and experiments have been carried out in order to prove what is said in ancient texts about female khomāhan. This research shows that female khomāhan is the equivalent of the Latin word hematite. According to researches, this term in ancient Iran, in addition to hematite, was also referred to as other iron ore. In this study, it was found that the “male khomāhan” is equivalent to today's known mineral of the European word "goethite" and the word “magnetic and black khomāhan” refers to the word “Magnetite”.
