Pythias [d. 322 B.C.] : " The discoverer of Britain' 1 

 See Aoust, 18G6; and Markham, 1893. 



Pythias — the famous Greek navigator — made two voyages from Massilia 

 (Marseilles) to the western and north-western coasts of Europe. Of these 

 voyages he gave accounts in two works: (1) On the Ocean, and (2) the 

 Periplus ; of which, most unfortunately, fragments only survive as 

 quotations in the works of Strabo, Polybius, Eratosthenes, Hipparchus. etc. 

 Pythias undoubtedly visited Britain, and travelled over its southern part 

 — it is quite possible that he saw, or at all events heard of. Stonehenge. 



For some account of Pythias — in addition to the two authors named above 

 see Straszewicfr, " Pytheas de Marseille et la Geographie de son Temps," 

 Paris, 1836 ; also Bougainville ; D'Anville] Ukert, etc.

Describes the "Druid Stones, Sarsen Stones, or Grey Wethers " (p. 41). 

 They are especially numerous near Marlborough. Agrees with Prestwich 

 that these stones (now detached and scattered) are the remnants of a 

 stratum of Eocene Age which formerly extended over most of the chalk 

 area of the present Downs. The " greenstones " of Stonehenge " are of 

 the same nature as the igneous rocks of part of the Lower Silurian region 

 of N. Pembrokeshire, of Caernarvonshire, and of the Llandeilo flag district 

 of Montgomeryshire" (p. 44). 



1859. "Foreign" Rocks of Stonehenge. [See Long's 



Stonehenge, p. 70.] 



In a letter addressed to Dr. Thurnam, Prof. Ramsay remarks that " t ho 

 greenstone may possibly come from Devonshire, but such rocks are also 

 plentiful in [North Wales] . They also occur in X. Pembrokeshire." Adds 

 that Mr. Perkins (Vicar of Wootton-under- Kdgei considers that they were 

 brought from Brittany, and agrees that this is "possibly the oase."
