rock, closes again on the further side of that rock, and in its motion carries with it the clouds from all quarters and leaves them where it strikes.  And it is always full of thunderbolts from the great quantity of clouds which accumulate there, whence the rock is all riven and full of huge debris [Footnote 77:  Sudden storms are equally common on the heights of Ararat.  It is hardly necessary to observe that Ararat cannot be meant here.  Its summit is formed like the crater of Vesuvius.  The peaks sketched on Pl.  CXVI-CXVIII are probably views of the same mountain, taken from different sides.  Near the solitary peak, Pl.  CXVIII these three names are written goba, arnigasar, caruda, names most likely of different peaks.  Pl.  CXVI and CXVII are in the original on a single sheet folded down the middle, 30 centimetres high and 43 1/2 wide.  On the reverse of one half of the sheet are notes on peso and bilancia (weight and balance), on the other are the ‘prophecies’ printed under Nos. 1293 and 1294.  It is evident from the arrangement that these were written subsequently, on the space which had been left blank.  These pages are facsimiled on Pl.  CXVIII.  In Pl.  CXVI-CXVIII the size is smaller than in the original; the map of Armenia, Pl.  CXVIII, is on Pl.  CXIX slightly enlarged.  On this map we find the following names, beginning from the right hand at the top:  pariardes mo (for Paryadres Mons, Arm.  Parchar, now Barchal or Kolai Dagh; Trebizond is on its slope).

Aquilone —­North, Antitaurus Antitaurus psis mo (probably meant for Thospitis = Lake Van, Arm.  Dgov Vanai, Tospoi, and the Mountain range to the South); Gordis mo (Mountains of Gordyaea), the birth place of the Tigris; Oriente —­East; Tigris, and then, to the left, Eufrates.  Then, above to the left Argeo mo (now Erdshigas, an extinct volcano, 12000 feet high); Celeno mo (no doubt Sultan Dagh in Pisidia).  Celeno is the Greek town of KeAouvat—­ see Arian I, 29, I—­now the ruins of Dineir); oriente —­East; africo libezco (for libeccio—­South West).  In the middle of the Euphrates river on this small map we see a shaded portion surrounded by mountains, perhaps to indicate the inundation mentioned in l. 35.  The affluent to the Euphrates shown as coming with many windings from the high land of ‘Argeo’ on the West, is the Tochma Su, which joins the main river at Malatie.  I have not been able to discover any map of Armenia of the XVth or XVIth century in which the course of the Euphrates is laid down with any thing like the correctness displayed in this sketch.  The best I have seen is the Catalonian Portulan of Olivez de Majorca, executed in 1584, and it is far behind Leonardo’s.].  This mountain, at its base, is inhabited by a very rich population and is full of most beautiful springs and rivers, and is fertile and abounding in all good produce, particularly in those parts which face to the South.
