Re: Turned Capital letter L (pointing to the left, with serifs)

[Raymond Mercier]

The sign described as like 7 is surely a cursive form of π. The form used by 
Gauss (Disquisitio de elementis ellipticis Palladis) is much the same as that 
shown in manuals of Greek Palaeography as a cursive π. This is given by E.P. 
Thompson in two works, An Introduction to Greek and Latin Palaeography, Oxford, 
1912, p.83, and  A Handbook of Greek and Latin Palaeography, Chicago, 1975, p. 
95.
