Working through another C.A. Smith's story, I fail to understand what "even thus" mean. Not even Googling could answer the question because most sources just state the examples with no hints of the meaning.
Flowers of many hues had been strewn upon the bier, and their fragrance filled the air with a drowsy languor, with an anodyne that seemed to drug my heart and brain. Such flowers had been cast on the bier of Mariel; and even thus, at her funeral, I had been overcome by a momentary dulling of the senses because of their perfume.
The whole paragraph is not completely clear because the second sentence seems to just repeat what is in the first one, but maybe the "even thus" phrase will - once I understand it - change it?
