During the first half of
the seventeenth century, when the nations of Europe were quarreling over who
owned the New World, the Dutch and the Swedes founded competing villages ten
miles apart on the Delaware River. Not long afterward, the English took over
both places and gave them new names, New Castle and Wilmington.
For a century and a half the two villages grew rapidly, but gradually
Wilmington gained all the advantages. It was a little closer to Philadelphia, so
when new textile mills opened, they opened in Wilmington, not in New Castle.
There was plenty of water power from rivers and creeks at Wilmington, so when
young Irenee DuPont chose a place for his gunpowder mill, it was Wilmington he
chose, not New Castle. Wilmington became a town and then a city —a rather
important city, much the largest in Delaware. And New Castle, bypassed by the
highways and waterways that made Wilmington prosperous, slept ten

[单项选择]
The history of responses to the work of the artist Sandro Botticelli (1444 ～ 1510) suggests that widespread appreciation by critics is a relatively recent phenomenon. Writing in 1550, Vasari expressed an unease with Botticelli’s work, admitting that the artist fitted awkwardly into his evolutionary scheme of the history of art. Over the next two centuries, academic art historians defamed Botticelli in favor of his fellows Florentine, Michelangelo. Even when anti-academic art historians of the early nineteenth century rejected many of the standards of evaluation adopted by their predecessors, Botticelli’s work remained outside of accepted taste, pleasing neither amateur observers nor connoisseurs. (Many of his best paintings, however, remained hidden away in obscure churches and private homes. )
The primary reason for Botticelli’s unpopularity is not difficult to understand: most observers, up until the midnineteenth century, did not consider him t
