How does Jonson use allusion in the poem, To Penshurst?

Sir Philip Sidney was a poet, soldier, and courtier during the reign of Elizabeth I. He is perhaps the most famous and notable member of the Sidney family, and was celebrated long after his death in 1586 for his involvement in English culture and politics. Sidney was often considered an exemplar of the older chivalric order in England, and hailed as an ideal participant in the development of the English nation. While he does not appear explicitly in "To Penshurst," Jonson alludes to his accomplishments throughout the poem and uses him to idealize the Sidney family more generally.
