In the days bevor the journey to Erebor, Thorin and his Compagnon lived a normal life. They had the luck to find a nice Cave with a lot of stuff to dig :-)
As you see on the main foto Fili was a excelent blacksmith!
We do not know if the dwarfs are interessed in astrology. But on the ground of there cave the sign of Taurus showed up.
The planet said to be ruler of Taurus is Terra. That fits because the dwarfs are working in or under the Earth (Terra).
Thorin and Bifur are digging the worth out of the rock...
.. and Bombur as always is having a snack, but ups he has finished now.
