Together with him, Smaragd built the Premontre monastery church of Zsámbék around 1220.
[1] During the foundation, Smaragd donated his estates Szentkirály (within Esztergom), Marót, Perbál, Répás (today a borough of Sajópálfala), Szörény, Zsámbék, Ság, Seregélyes and Szerdahely to the monastery.
Aynard I served as ispán of Valkó County from 1244 to 1246, while Gilét I was count of the tárnoks ("comes udvornicorum").
Both of them belonged to the retinue of Queen Maria Laskarina, wife of Béla IV of Hungary.
[4][5] Smaragd served as judge royal (iudex curiae) between 1205 and 1206.
