Today is the feast day - along with that of St Anastasius - of St Vincent, the protomartyr of Spain, who is said to have suffered in 304.
He is one of the three great deacon martyr saints along with St Stephen and St Lawrence, although he is perhaps less well known than the other two.
Devotion to him is focused on Saragossa, where he was deacon, Valencia where he was martyred and Lisbon where he was to eventually be enshrined.
I wrote about his depiction in art in 2016 in my post, although unfortunately not all the pictures downloaded successfully, at St Vincent
I have also come across a 2019 post from AnaStpaul about St Vincent has some of the same well-known images and others besides and can be seen at Saint of the Day – 22 January – St Vincent of Saragossa (Died 304) – Protomartyr of Spain
Wikipedia has an account of the magnificent and fascinating mid-fifteenth century paintings now known as the St Vincent panels in Lisbon, which depict the martyr - twice - surrounded by the identifiable elite of Portugal in the reign of King Afonso V and which can be viewed at Saint Vincent Panels
