Yes, lingam meaning a lot of things, stain, mark and male gender, but to have meaning as a dye is not an enormous leap. The debate on being a phallic symbol is on, I am not saying that it is not as well, considering the wealth and power that it brought, how does it look.
My point is, that Murex dye and Murex dyed goods were amazing value for millennias in antiquity. Just as gold, treasure. It involved a lot of labour, a lot of people whos income it provided, the people who picked them, smash them to make the dye, the people who provided the fabrics. Just see the effort we go to make vine or mine ore. A lot of people lot of effort and infrastructure. I am just saying, that we can understand old cultural accounts better, the dynamics of ancient world if we start including murex as a serious factor. Abrahamic tradition, looking for brt with gods and their offerings, worship make sense all of the sudden, smelly offering makes sense from Cain, the importance of mirh and frankincense makes sense(it was a stinky business, rotting shelfish so odour controll and cosmetics was a good supporting industry) The Hebrew history makes sense, like why as murex professionals expert dyers were taken by dynasties, reasons for exodus makes sense and the promised land too. The Vedic tradition and living customs makes sense, still alive, remnants of thousands of years of activity and routine becomes ritual. I do not want to, but thats what it tells me. Dont want to be repetative, but it would drive exploration for new murex sites, the native inhabitants included in a world wide trade, calendars thought and syncronised, technology shared, knowledge shared, populations had a chance to offer a product to the civilised world, inclusion. It was an important driving force and I do believe that we can find explanation to lots of religious and cultural reference.
So I do not want to assign utilitarian purpose to it, but it has. We do make things to use them. It makes more sense to have a very important tool and becomes irreverent, that later becomes else. To have a very strong industry what becomes obsolete but carries on as rituals.
Thank you again for your thoughts, I feel very alone and frustrated as I do not have anyone around me who like history, or would understand my references.
