GESTA ROMANORUM (the exploits of the Romans), a collection of short didactic stories, not however solely Roman, written in the Latin tongue, probably towards the close of the 13th century, the authorship of which is uncertain, though it is generally recognised as of English origin; the stories are characterised by naive simplicity, and have served as materials for many notable literary productions; thus Shakespeare owes to this work the plot of Pericles and the incidents of the caskets and the pound of flesh in the “Merchant of Venice,” Parnell his “Hermit,” Byron his “Three Black Crows,” and Longfellow his “King Robert of Sicily.”

GHATS, or GHAUTS, EASTERN AND WESTERN, two mountain ranges running parallel with the E. and W. coasts of S. India, the latter skirting the Malabar coast between 30 and 40 m. from the sea, rising to nearly 5000 ft., and exhibiting fine mountain and forest scenery, and the former skirting the E. of the Deccan, of which tableland it here forms the buttress, and has a much lower mean level; the two ranges converge into one a short distance from Cape Comorin.
