Because it was one of the Frisian Geertmen settlements during their remigration to Texland from Geertmania in North-west India.
This is our earliest history.
Wr-alda, who alone is eternal and good, made the beginning. Then commenced time. Time wrought all things, even the earth. The earth bore grass, herbs, and trees, all useful and all noxious animals. All that is good and useful she brought forth by day, and all that is bad and injurious by night. After the twelfth Juulfeest she brought forth three maidens:
Lyda out of fierce heat.
Finda out of strong heat.
Frya out of moderate heat.
When the last came into existence, Wr-alda breathed his spirit upon her in order that men might be bound to him. As soon as they were full grown they took pleasure and delight in the visions of Wr-alda. Hatred found its way among them. They each bore twelve sons and twelve daughters—at every Juul-time a couple. Thence come all mankind.
Next I need to leave some part of the scripture out because it gets too long to post.
Lyda was black, with hair curled like a lamb's; her eyes shone like stars, and shot out glances like those of a bird of prey……..Poor Lyda! She turned grey by her mad behaviour, and at last she died heart-broken by the wickedness of her children. Foolish children! They accused each other of their mother's death. They howled and fought like wolves, and while they did this the birds devoured the corpse. Who can refrain from tears at such a recital?
Finda was yellow, and her hair was like the mane of a horse. She could not bend a tree, but where Lyda killed one lion she killed ten……..Despicable people! The laws that Finda established were written on golden tables, but the object for which they were made was never attained. The good laws were abolished, and selfishness instituted bad ones in their place. O Finda I then the earth overflowed with blood, and your children were mown down like grass. Yes, Finda! those were the fruits of your vanity. Look down from your watch-star and weep.
Frya was white like the snow at sunrise, and the blue of her eyes vied with the rainbow……. Obedient children! When they came to themselves again, they made this high mound and built this citadel upon it, and on the walls they wrote the Tex, and that every one should be able to find it they called the land about it Texland. Therefore it shall remain as long as the earth shall be the earth.
