The founder of the sect of Stylites, the fanatical Pillar-saint, Simeon Sisanites of Syria, the son of a Syrian herdsman, is said to have passed thirty-seven years in holy contemplation, elevated on five columns, each higher than the preceding. He died in the year 461. The last of the pillars which he occupied was 40 ells in height. For seven hundred years there continued to be followers of this mode of life, who were called _Sancti Columnares_, or Pillar-saints. Even in Germany, in the see of Treves, attempts were made to found similar aërial cloisters; but the dangerous practice met with the constant opposition of the bishops.[GX] Footnote 33: p. 14.—“_Towns on the banks of the Steppe-rivers._” Families who live by raising cattle and do not take part in agricultural pursuits have congregated together in the middle of the Steppe, in small towns, which, in the cultivated parts of Europe, would scarcely be regarded as villages. Among these are Calabozo, which, according to my astronomical observations, is situated in 8° 56′ 14″ north lat., and 67° 43′ west long.; Villa del Pao (8° 38′ 1″ north lat., and 66° 57′ west long.); Saint Sebastian, and others. Footnote 34: p. 14.—“_Funnel-shaped clouds._” The singular phenomenon of these sand-spouts, of which we see something analogous on the cross roads of Europe, is especially characteristic of the Peruvian sandy desert between Amotape and Coquimbo. Such dense clouds of sand may endanger the safety of the traveller who does not cautiously avoid them. It is remarkable that these partial and opposing currents of air should arise only when there is a general calm. The aërial ocean resembles the sea in this respect; for here, too, we find that the small currents (_filets de courant_) in which the water may frequently be heard to flow with a splashing sound, occur only in a dead calm (_calme plat_). Footnote 35: p. 14.—“_Increases the stifling oppression._” I have observed in the Llanos de Apure, at the cattle farm of Guadalupe, that the thermometer rose from 92°.7 to 97°.2 Fahr. whenever the hot wind began to blow from the desert, which was covered either with sand or short withered grass. In the middle of the sand-cloud the thermometer stood for several minutes together at 111° Fahr. The dry sand in the village of San Fernando de Apure had a temperature of 126° Fahr.
