A. W. Yrjänä

[4] He has also collaborated with Sanna Kurki-Suonio and Henrik Otto Donner in composing a musical piece for the celebration of the 150th birthday of the Finnish national epic Kalevala.

Tommy Tabermann, one of Finland's most popular contemporary poets, commented that the book "surprised him" and referred to Yrjänä as a "very promising fellow".

[7] In response to criticism that the book contained too much obscure references for the average reader, Yrjänä published an appendix to Arcana on the CMX web site.

Jukka Koskelainen of Helsingin Sanomat appreciated Yrjänä's exotic imagery and knowledge of different philosophies and religions, although he felt that the writer's language lacks the finer nuances of some of his more experienced colleagues.

[14] In Mechanema (2006), the themes of alchemy, metaphysics and ancient mythology were largely put to the background and accompanied by a melancholy everyday tone.
