Naming
It would appear Turner named all his paintings. Generally with a
name that captured the spirit of the theme. With the passing of time,
some of these names have been lost. Some paintings have been
renamed for sale. This has led to the same painting appearing
under different names. “Faithful Friend” (1890) would appear more
likely than the alternate name of “Pioneer with fledgling”. There are
a number of titles using the word “Pioneer” - there is some doubt
Turner would have referred to his subjects as “Pioneers”.
A good example is “Fire stage coach and sheep”(1880) – the original
title was more likely something like … “Unwanted Delay”.
