as some here ... like the "wonderful"
I'll use it, though ... at least ... everything is possible, only God knows
in South Algerian Sahara, among the Tuareg territories lived a time an hermit (1904-1916)
he was belong from the old French nobility, before being a monk, he was a French military officer
after twelve years spent in the wilderness of Sahara, one day a Tuareg had killed him
all this to say that, the monastic order that he had tried to create, had the same symbol;
-
the cross overcoming a heart
his name; Charles Eugène de Foucauld de Pontbriand
he published under a pseudonym the first Tuareg-French dictionary.
The work of Charles de Foucauld is a reference to the knowledge of the Tuareg culture.
attention 
I do not necessarily connects the "Katuba" with the above,
I note just some coincidences
- Place; Sahara
- Person; Touareg = takouba
- Symbol, worn by the Father eddy Sahara, the French army in these places, and what we saw on the sword
to each one to do his own scenario
