POTATO ("SECOND BREAD")--my tour guide of Peterhof Palace (CROWDED!!) said that the potato was introduced to Russia during Peter's reign, and it was called the "second bread."

OTTOMAN/DIVAN--a room at the Peterhof Palace is known as the Divan Room.  OED has 1702 for "divan."  Queen Catherine introduced it during the 1700s, and my tour guide called it an "ottoman."  OED has "ottoman" from 1806.  Check this thing out (on the web? in books?).  Is it an ottoman?  Was it called an ottoman?
