bowed string instruments
The arpeggione is a six-stringed musical instrument fretted and tuned like a guitar(E-A-d-g-b-e' ).
The instrument is sometimes also called a "guitar violoncello".
The lirone is the lira family of instruments that was popular in the late 16th and early 17th centuries. It is a bowed string instrument with between 9 and 16 gut strings and a fretted neck.
Also known as "lira da gamba".
The viola da gamba is an Italian word for leg viola. It is called by this name because it is played by sandwiching the main body between both legs to fix it.
Also called viol in English, viola, which is used in modern orchestras, has the same etymology.
There are also musical instruments named vielle and vihuela, which are not only bowed instruments but also plucked string instruments, and the name "vi what" has been widely used depending on the times and regions. For this reason, even if it is called viol, I don't know which instrument it is. So maybe he often uses the Italian name Viola da Gamba for this instrument.
The viola di bordone is a bowed string instrument similar to the viol (viola da gamba), but distinguished by an extra set of plucked strings. It was in regular use in Europe until the end of the 18th century.
Also known as "baryton".
