Hotteterre, Principes de la flûte traversière…, Paris, 1707. Ex. p.23 #2.
Note: This shows the standard pattern for dotted triplets (corresponding to | V | ), as often found in French Gigues. The main thing is that the articulation occurs from the short note to the faster note, using t r. One difference between Hotteterre and Freillon-Poncein, as shown at the end of theis example, is that Hotteterre changes the pattern for the leap (using t t) whereas F-P. does not.
Quantz, Versuch einer Anweisung die Flöte traversiere zu spielen (Berlin, 1752)
This shows the same pattern of articulating across the beat.

Note: F-P uses t r for anticipation/resolutions, even those with ornamented anticipations. He also allows r on notes which are apparently to be trilled, whereas Hotteterre gives a specific injunction against such a practice. (See the Standard Patterns page where Hotteterre breaks the pattern for a trilled note (marked +) as well as for final note.)
