 of swarms got naturally the most mixed up with 

 the Iberian aborigines, and the result of their gradual

 and Hellenic peoples. In Spain the aborigines held 

 their own most successfully, and hence the mixture 

 was recent enough to be recognised by Roman 

 historians, who called the Spaniards Kelt-Iberians; 

 but elsewhere it was accomplished so early as to 

 be forgotten before people began to write history. 

 It has been fashionable to sneer at zealous Irish 

 writers for their propensity to find traces of the 

 Kelts everywhere. But there is no doubt whatever 

 that the Kelts were once a very widely diffused 

 people. They have left names for rivers and moun- 

 tains in almost every part of Europe. The name
